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:
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.
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:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\ CurrentVersion\Explorer
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.
When set to 1, Boot pop-up messagesare suppressed.
The default is 0.
Add value ErrorMode as a REG_DWORD.
0 - All system and application errors Pop-up (this is the default).
1 - Errors from system processes are suppressed.
2 - All system and application errors are suppressed.
Kill Shut Down Tracker
If you want to remove the Shutdown Event Tracker, the new .NET Server feature,and don't want to document the shutdowns in Event Logs especially in a testingenvironment, you can easily disable this feature in the Local Computer PolicyMMC. This console is not in the Administrative tools by default, so you have tocreate it:
1. Open a blank MMC console by typing mmc from the command line.
2. From the empty console, click the File menu and select Add/Remove Snap-in orpress Ctrl+M.
3. From the Add/Remove Snap-in page, click Add or Alt+D, choose Group Policy,select Local Computer and click finish.
4. From the Add Standalone Snap-in page, click Close. F
rom the Add/RemoveSnap-in page, click OK.
5. Expand Local Computer Policy, Computer Configuration, AdministrativeTemplates, System and in the right pane locate Display Shutdown Event Tracker.
6. Double-click the Display Shutdown Event Tracker and select Enabled. Changethe drop-down selector to Never.
7. Click OK to accept the policy change. Close the MMC console, saving it ifprompted to so.
Optimisze NTFS
Disable last access time by pointing regedit to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\ Control\FileSystem
and set 'eNtfsDisableLastAccessUpdate ' to 1 (DWORD).
Enable or disable boot defrag
Navigate to
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ Dfrg\BootOptimizeFunction
Select Enable from the list on the right.
Right on it and select Modify.
Change the value to Y to enable and N to disable.
Reboot your computer.
Classic Win2000 Style Search
HKEY_CURRENT_USER\Software\Microsoft\Windows\ CurrentVersion\Explorer\CabinetState
Add a new string (REG_SZ) called "Use Search Asst" -
set the value to"no" and you will have the classic win2000 search
Disable CD autoplay
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\ CurrentVersion\policies\Explorer
Create a new value called: NoDriveTypeAutoRun
Type is: DWORD
Value is: 0x000000b5 (181)
Start Menu Speed:
HKEY_CURRENT_USER/Control Panel/Desktop/
on the right you'll see MenuShowDelaychange the value there.
Then reboot
