This is the registry edit entry for the file you are going to made.
Just follow these simple steps and get a super fast computer.
Copy the following text:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters]
"EnablePrefetcher"="30"

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Dfrg\BootOptimizeFunction]
"Enable"="Y"

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\PriorityControl]
"Win32PrioritySeparation"="30"

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\AlwaysUnloadDLL]
"(Default)"="1"

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\WOW]
"DefaultSeparateVDM"="Yes"

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer]
"NoInstrumentation"="1"

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management]
"DisablePagingExecutive"="1"

[HKEY_USERS\.DEFAULT\Control Panel\Desktop]
"AutoEndTasks"="1"

Now copy this in Notepad(I personally prefer Notepad++, you can download it from sourceforge, I wont post the link, be active and get your smart ass up).
Save the file as Something.reg.

Note!!!!!!!!!
Dont forget the ".reg" extension( of cource without the quotes :) )
Now run the file it will show you a dialog box asking whether or not adding the information to the registry or not. Just press enter or click on yes.

Now restart your computer. The booting process will be superfast.
If you cant understand what i am talking about google some time for the windows registry.
Thanks for reading this post.
