How to disable and remotely remove Antivirus?
I
wanted to remove the antivirus programs remotely because the computers
are too far away and my chair is rather comfortable having been moulded
to my ample behind. I also wanted to do this removal silently to both
allow the end users to continue working undisturbed and as an added
bonus I don't have to talk to them and have them put me off because they
are just too busy at that moment.

How to remote control your home computer from work?
There’s always that time when you need desperately to get into your home computer from work, be it to get financial or tax information or just to kick off a download of that great movie your buddy just told you about. Most of us bound behind the corporate firewall can’t get to much of anything outside of 80 or 443 as far as ports go, besides that a lot of us don’t even have rights to install new software on our computers. So we need a hack that doesn’t require any installation on our work computer, but will allow most of us to terminal into our home computer.
The hack is to allow a remote desktop connection to your computer over port 443, which is the standard http ssl port, and is typically left open for internet browsing by the sys-admin. The hack should work on most Windows 2000/XP/Vista machines. This hack will not work if you’re serving up an SSL website out of your house. Keep in mind this hack requires editing the registry and if you don’t know what your doing or modify the wrong key it could severely trash your computer, please perform at your own risk.

How Windows Registry hack works?
Windows registry hacks are used to maintain the efficiency in theWindows operating system and to help enhance the security of thesystem. Registry hacks are located in the Windows registry whichcontains all of the files, settings, and configurations that controlthe Windows operating system.
The Windows registry provides a complete management system for the applications that run on the Windows operating system.Since the programs are dispersed throughout the operating system theregistry is capable of storing all the files in one location whichmakes it easier to work with the files that are associated with all ofthe applications running on the operating system.
How Registry Hacks Work
There are many different types of Windows registry hacks thatperform different functions when it comes to making the operatingsystem run more efficiently and securely.- Security Hacks: A security hack is a command typelocated in the registry that controls the access to certainapplications by other people that are using your computer. Althoughthere are other ways to restrict access to areas of your computer, asecurity hack provides an additional security enhancement by providingthe capability to disable the hidden administrator account. This is anaccount that exists in your operating system in addition to the usualadministrator account. Anyone that understands the operating system cangain access to areas you have restricted through this hidden account.
- CPU Time Saver: During usual computer operationsthere are several different programs using the central processing unitsimultaneously. When the programs are operating at the same time,Windows will distribute a period of CPU time before moving on to thenext application. This design is incorporated into the operating systemto allow your PC to run faster, however, sometimes there is a longertime span between switching applications. The CPU registry hack sets alonger duration for the central processing unit before it moves to thenext application.
- Encryption Hack: A few versions of the Windowsoperating systems allow you to encrypt files although it is a processthat involves a lot of steps. Deploying an encryption registry hackcuts back on the complexity of file encryption by providing a moreefficient method for encrypting your files.
- Hard Drive Access Hack: Some of the versions ofthe Windows operating systems take longer to access the hard drive ifit contains a massive amount of data and files. You can speed up thetime it takes to access the hard drive by deploying a hard drive accesshack.

How to increase (set 75 GB) store limit of exchange 2003?
Even though Exchange 2003 has been very stable for us, SP2 isalready installed on the test server here and I’ve been doing some reading todetermine how soon we’ll need to install it. The biggest positive I’ve foundyet is the increase in the mail database limit to 75GB on the Standard versionof Exchange 2003. This is a much-needed increase, and the only reason we’rerunning Exchange’s expensive Enterprise version is our need to accomodate hugeattachements from cour clients. I also have a personal client intelevision-services who will be thrilled to know their four users can now storevideo clips in exchange, instead of constantly archiving to one big folder onthe network.
The 75GB database limit isn’t setautomatically when SP2 is installed. After all, 75GB exceeds a lot ofexpectations of the Exchange server and the disk space on most older servers.Since so few admins read the documentation, they might miss this change andlock up their servers. The registry change below, can be set to anyvalue between 1 and 75, the maximum size of the Exchange database in GB’s. Bydefault Exchange 2003 SP2 pushes the default database size to about 18GB, whichis the original 16GB maximum plus a 10% over-limit buffer to keep mail comingin while Exchange floods the system with alerts about the database size.
To expand the Exchange database, orset a limit between 1 & 75GB:
HKLM\SYSTEM\CurrentControlSet\Services\ MSExchangeIS\SERVER_NAME\Private-STORE_GUIDTo change the Public store limit, navigate to
HKLM\SYSTEM\CurrentControlSet\Services\ MSExchangeIS\SERVER_NAME\Public-STORE_GUID
2: In the event your Exchange server has more than one private or public store the GUID of each store can be found by running ADSIEDIT.msc and navigating to:
CN=MAILBOX_STORE_NAME(SERVER_NAME),CN=STORAGE_GROUP_NAME, CN=InformationStore,CN=SERVER_NAME, CN=Servers,CN=FirstAdministrative Group,CN=Administrative Groups,CN=Organization name,CN=MicrosoftExchange,CN=Services,CN=Configuration,DC=domain,DC=com
SERVER_NAME,STORAGE_GROUP_NAME, and MAILBOX_STORE_NAME reflect the mail store to bechanged. Then take note of the objectGUID:… value for that mail store.
3: Create a new REG_DWORD value in the registry key for the correct GUID. Name it “Database Size Limit in Gb” and set the value from 1 to 75.
4: Assuming you are newly setting the “Database Size Limit in Gb” value, it will be detected at the next size check. Reboot the Information Store service for immediate recognition.
By setting the “Database Size Limitin Gb” key the mailbox store will not exceed that value. When the mail storereaches 90% off that value, a default 10% buffer is allowed, it will begin tolog event ID #9689 to notify you that the store limit has been reached.
Oncethe mail store does reach the maximum limit the first size check, which happensevery 24 hours at 5am, will not take the database offline. The second sizecheck will dismount the store that exceeds the limit.
Both the % of the mail store used asa buffer and the time of the database size check can be changed within the sameGUID registry key referenced above.
To set either, create a REG_DWORD valuenamed “Database Size Buffer in Percentage” or “Database Size Check Start Timein Hours From Midnight”.
Set their values from 1 to 100 or 0 to 23 to change,respectively, the buffer % or the offset from midnight for the size check.
The Exchange 2003 Enterpriseinformation store can also be limitted by the “Database Size Limit in Gb” key.
The valid range of values is 1 to 8000. If the key is not set, the defaultvalue is 8000GB.
It still amazes me that the ExchangeSystem Manager doesn’t have settings for either “max. database size” or “min.disk space remaining on server”.
Isn’t that the whole point of Exchange? …thatit’s faster and easier to run because it doesn’t require the amount ofexperience and forethought that Postfix does.
Update: This same registry tweak is also supported on Windows SmallBusiness Server 2003 (SBS). See the comments below for a link the the SBS 2003FAQ.

All-In-One Windows 2003 Performance and Security Tweaks
Tweaking in windows is very useful when your system can't perform accurate work on accurate time n also they are useful if you want to secure your system from Viruses or Hackers.
Here is a complete list of all Security and Performance tweaks of Windows Server 2003....
With that tweaks you can use your computer as a AMD or Itanium ....
These tweaks is only an overview, for all tweaks (Performance and Security) you ,must download these files :
Windows 2003 Performance and Security Tweaks :
Turn off Indexing to speed up Server2003
To make searching your hard drive faster Server 2003 keeps a record of all thefiles on the hard drive. The downside to this is it will slow down normal filecommands such as open, close, etc. If you don't do many searches (like me) itis better to turn off this feature. Here's how:
-Open my computer
-Right click your hard drive icon and select properties.
-At the bottom of the window find "Allow indexing service to index this diskfor faster searches" uncheck this and click ok.
-A new window will pop up, select apply to all folders and subfolders. It willtake a minute or two for the changes to take affect...

you are done.
Prioritizing your IRQs
The essential components in your computer have an IRQ number assigned to them.With this tweak we can increase the priority given to any IRQ number, improvingthe performance of that component. This tweak is commonly used for the SystemCMOS/real time clock, which can improve performance across the board. First ofall, decide which one of your components you want to give a performance boostto. Next, you have to figure out which IRQ that piece of hardware is using.Doing this is simple. Just go to Control Panel, then open the System panel (Youcan also press the shortcut of Windows Key +Break).

Click on the Hardware tab, then on the Device Manager button.
Right click on the component that you want to discover the IRQ for and thenclick Properties, and then onto the Resources tab.
You now can see which IRQ this device is using. Remember this number and closedown all of the dialog boxes that you have opened, fire up RegEdit. Next,navigate to:

You now can see which IRQ this device is using. Remember this number and closedown all of the dialog boxes that you have opened, fire up RegEdit. Next,navigate to:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\ Control\PriorityControl
You will need to create a new DWORD value - called IRQxPriority (x is theIRQ number), finally set the data to 1.
Now restart and see the new improved performance. We recommend tweaking theCMOS, because it improves all around performance but the choice is up to you.You can prioritize more than 1 IRQ but it is definitely not recommended. Youcan easily remove this tweak by simply deleting the value that you originallycreated.
Memory Performance Tweaks
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\ Control\SessionManager\MemoryManagement
System Cache Boost
Note: As with the above tweak, you should have at least 256MB of RAM beforeattempting to enable the LargeSystemCache tweak.
When changing the value of the key LargeSystemCache from 0 to 1 you tell Sever2003 to allocate all but 4MB of the systems memory to the file system cache.
This simply means that the Server 2003 Kernel can run in the memory,significantly improving overall speed.
The 4MB of memory left is used for diskcaching, but if for any reason more is needed, Server2003 allocates more.
Thistweak improves performance a bit but can, this tweak can degrade performance insome intensive app's.
Input/Output Performance
Note: As with all these memory tweaks, you should only use this if you have256MB or more of RAM.
This tweak is only beneficial to people running a server, it improvesperformance while a computer is performing large file transfer operations.
Input/Output Performance
Note: As with all these memory tweaks, you should only use this if you have256MB or more of RAM.
This tweak is only beneficial to people running a server, it improvesperformance while a computer is performing large file transfer operations.
Bydefault, the value does not appear in the registry, so you will have to createa REG_DWORD value called IOPageLockLimit.
The data for this value is in bytes,and defaults to 512KB on machines that have the value.
Most people using thistweak have found maximum performance in the 8 to 16 megabyte range but youshould play around with the value to find whatfs best suited for you.
Rememberthat the value is measured in bytes, so if you want, 8MB allocated, itfs8*1024*1024 = 8388608.
Unloading DLLs
Explorer can cache DLL files in memory for a length of time after they havefinished being used. This results in giant amounts of memory being taken up byDLL files that are not even in use. Fix this by going to Windows Server 2003Registry Editor and navigating to:

Create a new sub-key called AlwaysUnloadDLL with a default value of 1.
If you want to disable this, just delete the key you made.
Disable Application/System Popup messages on Windows Startup
You can control what errors pop-up to interupt you by using the followingregistry keys (errors are still recorded in the event logs):
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\ Control\Windows
Add value NoPopUpsOnBoot as a REG_DWORD.

How to automatically login via 'administraton' a/c?
Well here's the trick which you can use to prove that Windows XP is not at all secure as multi-user operating system. Hacking the system registry from any account having access to system registry puts you in to the administrator account.
Steps:
1) Open Notepad
2) Copy the CODE section n paste into Notepad
CODE:
REGEDIT 4
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon]
"AutoAdminLogon"="1"
3) Save it with .reg extension (Like :- auto.reg)
4) After saving , double click on that file.

Windows Server 2003 Registry tweaks
Advanced users of Windows XP are used to digging around in the Registry looking for ways to tweak performance or push the envelope of Windows' abilities. Provided you back up your Registry before hacking it, no harm usually comes from such endeavors. What about tweaking servers though? What gains can be achieved by making Registry modifications to Windows Server 2003 and its various services such as Terminal Services, Internet Information Services, networking subsystem, and so on? Here are three of my favorite Windows Server Registry tweaks and the reasons you need to know about them. Plus, along the way, we'll learn a bit about the correspondence between the Registry and Group Policy. But please make sure you back up your Registry before you try any of these tweaks, just in case you make a mistake.
Monitor Winlogon Activities with Verbose Status Messages
What's going on when you start up your server?
Windows is notoriously secret about many of its activities, but by enabling verbose messages for the Winlogon service, you can closely monitor what's happening when your server boots up or shuts down, or when you log on or off the machine. Here's how to do it.
First, find the following Registry key:
HKLM\SOFTWARE\Microsoft\ Windows\CurrentVersion\Policies\System
Create a new REG_DWORD value here named verbosestatus and assign it the value 0x01. Now when you log on, log off, start up, or shut down your machine, you should see extra information describing what services are starting and what other activities are taking place on your machine. If you don't see this extra info, check the Registry key above again and see if there is a value named DisableStatusMessages present and if so, set this value to 0x00 or remove it.
Note that enabling verbose status messages for Winlogon requires a reboot.
A Brief Aside on Group Policy
Wait just a minute-- there's an easier way to do this!
If you want to enable verbose logging for a number of machines in a domain, use Group Policy instead of editing the Registry on each machine. Open the Group Policy Object (GPO) that's linked to the organizational unit (OU) where the computer accounts for these machines reside, and configure the following policy:
Computer Configuration\Administrative Templates\System\Verbose vs normal status messages
Also check the following policies:
Computer Configuration\Administrative Templates\System\Remove Boot / Shutdown / Logon / Logoff status messages
You can see that these two policies do the same thing as the two Registry values we looked at previously. That's not surprising--the Administrative Templates section of the machine or user portion of a GPO is basically just a tool for modifying Registry settings on targeted computer and user accounts, and in a domain environment, it's much easier to tweak the Registry by using Group Policy than to use Regedit.
Lightweight Domain Controllers at Branch Office Sites
Windows 2000 Server had some problems with domain controllers at remote sites, particularly when universal groups were used. If the domain controller at your remote site was a global catalog server, it generated a lot of replication traffic over the WAN, which could swamp a slow link from time to time. And if your domain controller wasn't a global catalog server, then users at your site might have experienced slow logons as their universal group memberships were enumerated by a global catalog server at headquarters.
Windows Server 2003 solved all this by allowing domain controllers to cache universal group membership lists; that way, you could reduce WAN traffic by not having to make your remote DC a global catalog server. Plus, you got increased availability because users at your site could still log on even if the link went down.
But there's an alternative to using universal group caching that involves changing the following Registry key on the domain controller at your remote site:
HKLM\SYSTEM\CurrentControlSet\Control\Lsa
Create a new REG_DWORD value here named IgnoreGCFailures and assign it the value of 0x01. Then reboot your domain controller.
The result? You've essentially turned your domain controller into the Windows Server 2003 equivalent of a Backup Domain Controller (BDC), which was a DC on the old Windows NT 4.0 platform that contained a read-only copy of your accounts database. In other words, the users at your remote site will now be able to log on to this domain controller despite the fact that it isn't a global catalog server, even when your WAN link goes down--and even if they are members of universal groups. The catch, though, is that if you use this hack, then you shouldn't use universal groups, because a security hole can result (users may get access to resources they shouldn't).
Why would you want to do this? Why not just enable universal group caching for the remote site?
The main reason is that configuring this Registry value reduces the hardware requirements for your remote domain controllers (think NT 4.0, where BDCs needed less beefy hardware than your PDC). This can be significant if your company has lots of small sites scattered around the country. For more information regarding this scenario, see this article in the Microsoft Knowledge Base.
Broadcasting Server Descriptions
Finally, here's a lightweight tweak that can really make a difference to your users, especially if you have a number of file servers they need to find and access regularly on the network.
I'm thinking here of the typical mid-sized business that still has four file servers running Windows 2000 Server, two running Windows Server 2003, and maybe even a few still running (eek!) Windows NT 4.0 Server. If you're still one of these shops, and you've run out of drive letters for mapping network drives to shares on your servers using logon scripts, then your users are probably stuck browsing My Network Places to try to find the server they want so they can do their work, and that's brutal. Fortunately, this simple Registry hack will make life a lot easier for them. Look for this key:
HKLM\SYSTEM\CurrentControlSet\ Services\LanmanServer\Parameters
If a REG_SZ value named srvcomment doesn't exist here, create it. Then open the value and enter a text string that describes the server, such as "Accounting File Server." This string will be displayed in the Comment field next to the server name the next time the user browses to this server using My Network Places.
Of course, you could always configure this setting on the server by right-clicking on My Computer, selecting Properties, selecting the Computer Name tab, typing "Accounting File Server" in the Computer Description textbox, and clicking Apply. But what fun is that?
How to display your Username and Computer Name on the 'My Computer'?
Here is a tip for those who like to hack the registry.
With this tip, every logged in User can see their Username and Computer Name on My Computer....
So, check it out....
Preliminary step : Show the 'My Computer' icon, go to Control Panel, Display, Desktop (Tab), Customize Desktop, Check My Computer.
Principle: Find the setting for the My Computer object in the HKey_Classes_Root, substitute two variables for the original setting.
Warning: This is a particularly difficult registry change to make so export the registry FIRST.
Regedit, File (menu), Export.
Getting Started
a) Use regedit to locate
[HKEY_CLASSES_ROOT\CLSID\ {20D04FE0-3AEA-1069-A2D8-08002B30309D}Rename LocalizedString to LocalizedString.Old.
I advice this step in case anything goes wrong and you want to revert to how it was.
b) Create a new VALUE type Expand_SZ.
Name it LocalizedString.
Set the value of LocalizedString to %Username% at %Computername%
Press F5 to refresh the 'My Computer', there is no need to logoff and certainly do not reboot.
THANKS....

Mastering The Windows XP Registry
REGISTRY is most important for our PC and also for softwares. Due to some reason, if regiistry is corrupted or deleted thn we can got System Failure Problem or PC hangup problem.
So, for better performance of Installed Softwares and System drivers its compulsary that we must make a copy of registries, so that we can recover it when its corrupted or deleted.
It make
The Recovery Console
The Windows XP Recovery Console is a tool that allows recovery from a number of failures.
Previously, all you could do was boot another copy of Windows XP and hack your way around, replacing files, even registry components, in the blind hope that you would somehow fix the problem.
With Windows XP, you have two tools to use:
The Recovery Console and The Safe Mode feature.The Recovery Console is a powerful, simple (no, that's not an oxymoron!) feature that is supplied with Windows XP, but it is not installed by default.
The Windows XP Safe Mode works in the same manner as the Safe Mode found in other versions of Windows. You can modify a number of system settings using Safe Mode (such as video modes). Installing the Recovery Console after the system has failed is quite like locking the barn door after the horse has been stolen—it really won't work that well.
Installing the Recovery Console
The Recovery Console must be installed before disaster strikes. It will be difficult (maybe even impossible) to install it after a disaster has reared its ugly head. So, let's install the Recovery Console right now.
First, you must use the Windows XP distribution CD (or share containing the appropriate files, if installing from a network device). The Recovery Console is installed using the winnt32.exe program. The winnt32.exe program is the same program that is used to install Windows XP; however, by selecting the correct option, you are able to tell winnt32.exe to not install Windows XP, but to install the Recovery Console instead.
Note It is not possible to install the Recovery Console at the same time as Windows XP. You must first install Windows XP, then install the Recovery Console. If you have multiple copies of Windows XP installed, it is only necessary to install the Recovery Console one time—the Recovery Console will work with as many copies of Windows XP as are installed.
Follow these steps to install the Recovery Console from the Windows XP distribution CD:
1. Insert the distribution CD and change into the i386 directory.
2. Run winnt32.exe using the /cmdcons option. Typically, no other options are needed, though some users may wish to specify source options, especially if installing from a network share rather than a hard drive.
3. The installation program contacts Microsoft to check for updates to this Windows XP component.
4. The winnt32.exe program opens the dialog box. This dialog box allows you to cancel the installation if you need to. Note that multiple installations of the Recovery Console will simply overwrite previous installations; in such cases, no error is generated.
5. If there are no errors, thn, The Recovery Console is ready for use at this point.
What's in the Recovery Console?
The Recovery Console consists of a minor modification to the boot.ini file, and the addition of a hidden directory on the boot drive. The added directory's name is cmdcons. The change to the boot.ini file is simply the addition of another line providing for a new boot option:
C:\cmdcons\bootsect.dat="Microsoft Windows Recovery console" /cmdconsThis option consists of a fully qualified file name (C:\cmdcons\bootsect.dat), a text description (Microsoft Windows Recovery Console), and a boot option (/cmdcons).
As everyone should be well aware, the Windows XP Boot Manager is able to boot virtually any operating system (assuming that the operating system is compatible with the currently installed file system).
How Windows XP Supports Booting other Operating Systems
Windows XP can be told to "boot" any directory or file location.
For example, the Recovery Console is saved in the cmdcons directory. In the cmdcons directory is a 512-byte file named bootsect.dat. Windows XP will treat a file named bootsect.dat exactly as if it were a hard disk's boot sector. In fact, one could, theoretically, copy the bootsect.dat file to a drive's boot sector location and cause that operating system to be booted directly.
One use for this technology is in a multiple-boot configuration where the other operating system or systems are not compatible with Windows NT (such as Windows 95/98/Me).
The Recovery Console does qualify as an operating system, though it is very simple—and limited.
A major question will always be this: Is the Recovery Console secure? In most situations, the Recovery Console is actually quite secure.
The user, at startup of the Recovery Console, is prompted for two pieces of information:
• Which Windows XP installation is to be repaired (assuming that there is more than one Windows XP installation!).
• The Administrator's password for that installation. The Recovery Console then uses the installation's SAM to validate this password to ensure the user has the necessary permission to use the system.
A situation comes to mind: if the Administrator's password is lost or otherwise compromised, not only may it be impossible to use the Recovery Console, but anyone with access to the compromised password could modify the system with the Recovery Console.
This is not really an issue, though. If the Administrator's password is lost, that's life. It will be difficult, if not impossible, to recover the password. If the security of the Administrator's password is compromised, then it will be necessary to repair the damage—changing the password is mandatory in this case.
In either case, the Recovery Console is no less secure than Windows XP is.
The cmdcons directory holds over 100 files.

How To Remove and Add Right-Click Menu Items from Files and Folders
Removing Items
A lot of programs you install will add themselves to the right-click menu of your files and/or folders. And most times, you have no choice in the matter and, as a result, your right-click menu can get very long with added items you don't even use. The last person I was helping with this had a right context menu so long that the Rename option was no longer visible!
Fortunately, you can easily remove those unwanted menu items, if you know the registry values to edit. And it's not at all difficult once you know the keys responsible for the additions.
For Files, the secret lies in the "context menu handlers" under the shellex subkey for "All Files" which, in the registry, is nothing but an asterisk - like a dos wildcard, which means the values entered apply to all files. It is at the very top of the Root key, right here:
HKEY_CLASSES_ROOT\*\shellex\ContextMenuHandlers
Click the the + sign next to the ContextMenuHandlers key, to expand it.
Now you will see some of the programs that have added items to your right-click menu. Simply delete the program keys you don't want.

Now you will see some of the programs that have added items to your right-click menu. Simply delete the program keys you don't want.
Yup! It's that simple. If deleting makes you uneasy, just export the key before deleting it. Or, instead of deleting the values, disable them. Simply double click the default value for the program on the right hand pane and rename the clsid value by placing a period or dash in front of it.
ie; - {b5eedee0-c06e-11cf-8c56-444553540000}
Then exit the registry, refresh, and right click a file to see if the item was removed from the menu.
Some programs - like WinZip or WinRar - will add several items to your right click menu but all of them will be removed by deleting or disabling their one context menu handler.
Note that the above key only applies to the right click menu of files.

To remove entries from the right click context menu of folders, you need to navigate to the Folder and Drive keys:
HKEY_CLASSES_ROOT\Folder\shellex\ContextMenuHandlers
HKEY_CLASSES_ROOT\Drive\shellex\ContextMenuHandlers
All you have to do is follow the same procedure as for Files - either disable or delete items you wish to remove.
HKEY_CLASSES_ROOT\Folder\shellex\ContextMenuHandlers
HKEY_CLASSES_ROOT\Drive\shellex\ContextMenuHandlers
All you have to do is follow the same procedure as for Files - either disable or delete items you wish to remove.
Adding Items
Adding Items to the right click menu of Files and Folders is also fairly simple using the Registry. It just involves the creation of a few new keys for each item you wish to add. You edit the same keys used for removing items. Let's use Notepad as an example of an item you'd like to add to the right click menu of all your files or folders.
For folders, go to this key:
For folders, go to this key:
HKEY_CLASSES_ROOT\Folder
Click the + sign next to Folder and expand it so that the Shell key is visible. Right click the Shell key and choose New>Key and name the key Notepad or whatever else you'd prefer (whatever the key is named is what will appear in the right-click menu). Now right click the new key you made and create another key named Command. Then, in the right hand pane, double click "Default" and enter Notepad.exe as the value.
Exit the registry, refresh, and right click any folder. Notepad should now be on the context menu.
For files, go here again:
Exit the registry, refresh, and right click any folder. Notepad should now be on the context menu.
For files, go here again:
HKEY_CLASSES_ROOT\*
Expand the * key and see if a Shell key exists. If it does exist, follow the same procedure as for folders. If it does not exist, you'll have to create a new Shell first. Just right click the * key and choose New - Key and name it Shell. Then right click the Shell key and continue on the same way you did for adding items to the right click menu of folders.
Once done, Notepad should appear as an option in the right click menu of all your files.
