Increase Windows XP Shutdown Speed

Windows XP stores a couple of values in its registry which are responsible for determining how long to wait before shutting down (killing) open applications and services once the shutdown command has been given.

By editing these two settings and changing them to lower values, you can considerably decrease the amount of time that Windows XP needs to successfully shut itself down. The first part of this tweak deals with setting the amount of time Windows will take to kill open applications on shutdown.

Open REGEDIT and navigate to ‘HKEY_CURRENT_USER\Control Panel\Desktop\’
Highlight the ‘WaitToKillAppTimeout’ value.
Set it to ‘1000′ (the default should be 20000).
Now highlight the ‘HungAppTimeout’ value
Set it to ‘1000′ also.

Increase Folder Cache

The default setting for WindowsXP is to cache the Explorer settings for 400 folders.
To increase it:

1. Start Regedit
2. Go to HKEY_CURRENT_USER\Software\Microsoft\Windows\ShellNoRoam
3. Change the vaule of BagMRU to whatever size you want (hex)

1000 - 3e8
2000 - 7d0
3000 - bb8
4000 - fa0
5000 - 1388

Disable Right Click on Start Menu

DISABLING THE RIGHT CLICK ON START MENU
Normally, when you right button click on the Start button, it allows you to open your programs folder, the Explorer and run Find.
In situations where you don’t want to allow users to be able to do this in order to secure your computer.
1.Open RegEdit
2.Search for Desktop
3.This should bring you to HKEY_CLASSES_ROOT\Directory
4.Expand this section
5.Under Shell is Find
6.Delete Find
7.Move down a little in the Registry to Folder
8.Expand this section and remove Explore and Open
Now when you right click on the Start button, nothing should happen.
You can delete only those items that you need.
Note: - On Microsoft keyboards, this also disables the Window-E (for Explorer) and Window-F
(for Find) keys.
