The Prefetch folder should be @
C:\WINDOWS\Prefetch
If it's not there, create one.
Highlight C:\WINDOWS | File | New | Folder | Name it: Prefetch | OK.
Task Scheduler needs to be set @ Automatic.
Start | Run | Type: services.msc | OK
Scroll down to and double click Task Scheduler | Startup type: Automatic |
Apply | OK |
Close Services.
Start | Run | Type: regedit | OK
Navigate to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory
Management\PrefetchParameters
Look for EnablePrefetcher in the right pane, if the value is not 3,
Double click EnablePrefetcher and change the value to 3.
Values are (0 = disabled, 1 = Application launch prefetching, 2 = Boot
prefetching, 3 = Both prefetching). 3 seems to be the preferred option.
Exit regedit
This will take effect on next reboot.
It will take three boots to rebuild the Prefetch file.
==============================
If for some reason layout.ini {C:\WINDOWS\Prefetch\layout.ini}does not get
recreated after three boots, try this:
Start | Run | Type: cmd | OK
Paste: rundll32.exe advapi32.dll,ProcessIdleTasks | Enter
At this point, the layout.ini should be rebuilt.
You can force a "boot optimization" by doing the following:
Start | Run Type: cmd | OK |
Type: defrag c: -boot | Enter
Open regedit and navigate to:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Dfrg\BootOptimizeFunction
OptimizeComplete Yes?
Set the LcnStartLocation to zero and the LcnEndLocation to zero
Run the defrag c: -boot again.
This time running "defrag" may take longer.
Again open regedit and navigate to:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Dfrg\BootOptimizeFunction
OptimizeComplete Yes?
LcnStartLocation
LcnEndLocation
Have the values changed from 0?
===========
By the way, Prefetch will purge itself of unused *.pf files.
You don't have to clean it yourself. If you do, *don't* delete the Prefetch
folder, just the contents.
