Decreasing Boot Time
[HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ Session Manager \ Memory Management \ PrefetchParameters]
Under this key there is a setting called EnablePrefetcher, the default setting of which is 3. Increasing
this number to 5 gives the prefetcher system more system resources to prefetch application data for
faster load times. Depending on the number of boot processes you run on your computer, you may get
benefits from settings up to 9. However, I do not have any substantive research data on settings above 5
so I cannot verify the benefits of a higher setting. This setting also may effect the loading times of
your most frequently launched applications. This setting will not take effect until after you reboot your system.

creating a script to run on shutdown that deletes the temp folder and history shaved 2.5 seconds boot time
Create a batch file by doing the following:
- Open notepad and enter the following lines:
RD /S /q "C:\Documents and Settings\"UserName without quotes"\Local Settings\History"
RD /S /q "C:\Documents and Settings\Default User\Local Settings\History"
RD /S /q "D:\Temp\" <--"Deletes temp folder, type in the location of your temp folder"
2) Save the fily and then rename is something like deltemp.bat
3) Now click Start, Run and type in gpedit.msc --->Computer Configuration --->Windows Settings
--->Scripts and double click on Shutdown --->Click Add and find the batch file you created and press ok to set the script

Automatically Killing Tasks on Shutdown
You know the drill. You start to shut down the computer, you wait a few moments, and then you see a dialog box asking if you want to kill an
application or service that is running. Instead of prompting you, you can make Windows XP take care of the kill task automatically. Here's how
1. Open the Registry Editor.
2. Navigate to HKEY_CURRENT_USER\Control Panel\Desktop.
3. Highlight the value AutoEndTasks and change the value to 1.
4. Close the Registry Editor.
