Last week I emptied my prefetch folder using this
Since then nothing has gone into the prefetch folder as it should.
Any ideas?
What service does prefetch run off? (however I havent shut any services down)

Please disreguard, I found the problem
Task Scheduler must be enabled for prefetch to do its thing.
Seems for some reason when using that program it turns off the service on its own and it must be manually turned back on again.

looks like Prefetcher is disabled. open registry editor and look for this key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters

check the value of EnablePrefetcher, to enable prefetcher, set it to 3.

it also relies on task scheduler

in addition, if you are partitioning, and your apps are on a differant partition then c, then prefetch won't do a hell of a lot, since the optimization involved doesn't cross volumes

Hey EP! All good with me, applying for Microsoft MVP right now, should have done this a while ago.

EP, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS

Been running around Quora lately, luv it there!
