Here we are going to disable some unnecessary services and also reducing the waiting time for the process
Improve XP Shutdown Speed
This tweak reduces the time XP waits before automatically closing any running programs when you give it the command to shutdown
Go to Start then select Run
Type 'Regedit' and click ok
Find 'HKEY_CURRENT_USERControl PanelDesktop
Select 'WaitToKillAppTimeout'
Change the value to '1000' and then click OK

Boot your computer faster
Press start->run then type msconfig and press enter.
Go to the startup tab. Here you will see a list of startup items. These are all the programs that automatically start when you boot your PC. It is these that slow down the boot up process.
So uncheck all the unwanted items like ms-office, messengers other utilities that u may not need at startup). Don't uncheck your antivirus software.
Speed up folder browsing
You may have noticed that every time you open my computer to browse folders that there is a slight delay. This is because Windows XP automatically searches for network files and printers every time you open Windows Explorer. To fix this and to increase browsing significantly:
1. Open My Computer
2. Click on Tools menu
3. Click on Folder Options
4. Click on the View tab.
5. Uncheck the Automatically search for network folders and printers check
6
7. Click Ok
8. Reboot your computer

Single click shutdown
Did you know that in Windows XP you can shut down your computer from the (eventually DOS prompt) command line box? Moreover, you can do this by clicking your mouse only once.
All you need to do is... right-click on an empty Desktop spot -> select New -> Shortcut -> type shutdown followed by a space, and then enter one or more of the parameters listed below -> click Next -> type a suggestive name for your new shortcut -> finally, click Finish.
This is the Shutdown.exe (located in %systemroot%System32, usually C:WindowsSystem32) syntax:
For example:
shutdown -s -c "Shutting down!" -t 3
tells your computer to shutdown after waiting for 3 seconds while the System Shutdown window will display text above in the Message area.
Optional: after you're done creating your customized shortcut for shutdown -> right-click on it -> select Properties -> enter your desired key "combo" in the Shortcut Key box (e.g. Ctrl + Alt + End) -> click OK/Apply.
