Windows prefetch option caches boot system files and application in to memory.
This is done to reduce the starting time of each individual applications like firefox, thunderbird etc...
But on a long run many application get in to prefetch folder that will cause too much initial startup time.
By default windows prefetch is enabled to cache both boot system files and application.
We can modify it to cache only boot system files..
Steps to do it
- start run dialog (windows key + R)
- type regedit and press enter
- in the regedit search for "PrefetchParameters"
else directly move to the folder
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters
- Select EnablePrefetcher, right click and select Modify
- Now enter 2 and press ok
Here you could enter 4 possible values
0 - Disabled : The prefetch system is turned off.
1 - Application : The prefetch only caches applications.
2 - Boot : The prefetch only caches boot system files.
3 - All : The prefetch caches boot, and application files.
