Manual Registry Tweak

Start menu >> search or run box >> browse down to the following key to open regedit.exe :

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\
Session Manager\Memory Management\PrefetchParameters


Find the EnablePrefetcher key on the right-hand pane, and change the value to one of these:

• Disable Caching: 0
• Cache Applications Only: 1
• Cache Boot Files Only: 2
• Cache Everything (default): 3

You have to restart your computer before this takes no effect. You might consider cancellation of the \ Windows \ Prefetch folder after making these changes to start with a new cache, but the next time will possibly be slow Because Windows will cache all again.
