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 increase dail-up speed? (Registry tweak...)
Dial up Download speed is low and some time it can be unused foradvanced user so to improve Dial up Download speed following registryediting is helpfull.
1. Direct in Regedit :
- Open:
- HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ Tcpip\Parameters
- “SackOpts”=dword:00000001
“TcpWindowSize”=dword:0005ae4c
“Tcp1323Opts”=dword:00000003
“DefaultTTL”=dword:00000040
“EnablePMTUBHDetect”=dword:00000000
“EnablePMTUDiscovery”=dword:00000001
“GlobalMaxTcpWindowSize”=dword:0005ae4c
OR
Open notepad & paste
Now save this file as speed.reg (in Windows).[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters]
“SackOpts”=dword:00000001“TcpWindowSize”=dword:0005ae4c
“Tcp1323Opts”=dword:00000003

Windows 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:
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.HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System
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:
Also check the following policies:Computer Configuration\Administrative Templates\System\Verbose vs normal 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.Computer Configuration\Administrative Templates\System\Remove Boot / Shutdown / Logon / Logoff status messages
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. This is not an issue if you have an enlightened view of things and have implemented the robust and totally revamped Distributed File System of Windows Server 2003 R2 on your 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:
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?HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters

Tutorial : REGEDIT
Regedit, You may be thinking "Regedit, what the hell is that?!"
or
If you have a reasonable amount of experience with computers "Oh awesome a page about what this program is."
What is Regedit?
Regedit is basically a program that lets you edit ceratin values in your computer (short for "Registry Editor").
BEWARE, DON'T JUST PLAY AROUND IN REGEDIT, SOME THINGS CAN SERIOUSLY HARM YOUR COMPUTER IF CHANGED OR REMOVED.
You can do really cool things with it such as remove buttons on your computer.e.g remove the shutdown option or make a message appear at startup.
Before you do anything you will need to know how to access the program.:
- So first go to your start menu
- Then click run
- Now type "regedit" without the quotes
How to display a legal notice on startup?
This is how to make a legal notice appear on startup:
- Open Regedit
- Navigate to
"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\system"
legalnoticecaption:"enter your notice caption here"
legalnoticetext:"enter your legal notice text here"
- Add admin user to welcome screen:
- Start the Registry Editor Go to:
HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion \ Winlogon \ SpecialAccounts \ UserList \
- Right-click an empty space in the right pane and select New > DWORD Value Name the new value Administrator.
- Double-click this new value, and enter 1 as it's Value data.
- Close the registry editor and restart.
Kill Processes immediately:
When logging off, you sometimes get an “End Task” dialog prompt, indicating a program that doesn’t shut itself down. You can suppress the prompts and have Windows kill these programs automatically when you log off.
In regedit, find key
HKEY_CURRENT_USER\Control Panel\DesktopLook for the value AutoEndTasks, and change it from 0 to 1.
No Shutdown:
Wanna play with your friends by removing the shutdown option from start menu in their computer.
- Regedit
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer
"NoClose"="DWORD:1"
Show Superhidden Files:
Even if you turn on show hidden files in Windows Explorer some files will remain hidden. These files are super hidden.
Set the registry value below to 1.
Unblock Regedit and CMD prompt:
Save this file is a .reg file then execute it
REGEDIT4
[HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionPoliciesWinOldApp]
"Disabled"=dword:0
[HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionPoliciesSystem]
"DisableRegistryTools"=dword:0
Memory Performance
Improving memory performance can be done simply by preventing your hard drive from being used for cache.
This is only useful with 256Mb or more of RAM.
Everything that you'll need to edit here can be found in
HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/Session Manager/Memory ManagementSo of course add
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management]to your *.reg file.
Disable Paging Executive
This will prevent pages sections from RAM going to the hard drive. If you have a large amount of RAM at least 256Mb (I suggest 512) you might want to keep the data in your RAM to improve your performance considerably due to reduced amount of hard drive swappage.
The entry that you will want to modify is called DisablePagingExecutive.
Changing this from 0 to 1 will keep the data in your RAM.
"DisablePagingExecutive"=dword:00000001
System Cache Boost
The XP kernel can be loaded into your RAM with a simple registry edit. This can greatly improve performance since the NT Kernel will always be in your RAM. With this edit you will allocate roughly 4Mb of your RAM for the kernel. Sometimes more RAM is used but most of the time it is only 4Mb.
The entry that you will need to find is called LargeSystemCache and you'll need to change this from 0 to 1 in order to enable this.
"LargeSystemCache"=dword:00000001To put both of these RAM tweaks into use you'll add something like this to your reg file
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management]
"DisablePagingExecutive"=dword:00000001
"LargeSystemCache"=dword:00000001
The XP Prefetcher
Windows XP has a service called the Prefetcher. It basically monitors the different programs that start during startup and helps them launch faster.
To find this tool browse to
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParametersThe important key is EnablePrefetcher. Default value for this is 3. You will want to try numbers between 1 and 6. 5 seems to work best for me but your mileage may vary.
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters]
"EnablePrefetcher"="5"
Ok, i think its GOOD for TWEAKER...
