Here's an easy way to delete your prefetch -- Automatically!!



1. Go into My Computer and go into your hard drive.



2. Right-click anywhere that a file is not and select the 'New' submenu and click 'Text Document'



3. Name it "deleteprefetch"



4. Double-click on the text file you just created.



5. Type "del C:\Windows\Prefetch\*.*" (without the quotes).



6. Go to File > Save As... and choose "All Files" from the "Save as Type" box and save it as "deleteprefetch.bat" 



7. You just created a batch file that will automatically delete all the files in your Prefetch folder. Congrats.



Note: It will prompt for you to delete the files (all, not one by one, luckily) so if you schedule for it to be done, make sure you'll be on the comp at the time of it's execution.
