Guest John Corliss Posted September 7, 2007 Posted September 7, 2007 My Prefetch folder keeps disappearing and I have Prefetch enabled. Is anybody else having this problem and if so, is there a fix for it? TIA -- John Corliss

This key has the following values: 0 = Disabled, 1 = Application launch prefetching enabled, 2 = Boot prefetching enabled, and 3 = Application launch and boot enabled. The prefetch folder is a "system" folder for the purpose of collecting hashes of startup files, to assist in faster startups. If the folder is somehow deleted is automatically rebuilt. There is at least one KB article, that I know of, that recommends deleting the prefetch files if they become corrupted. Mark

Thanks for replying Mark. Guess I should have stated that once I turned off Prefetching via that registry key (changed the value to "0") to see if there was any performance difference. There was, so I re-enabled prefetching. Seems like the folder disappears every time I reboot. At any rate, I just checked again (I did so before sending my OP) and the setting is still at 3. I now have a backed up copy of the folder in the Windows folder and might set up a restoration batch file to run at system startup. -- John Corliss BS206

It turned out to be a setting in a program I'm using. I have it all fixed now. -- John Corliss
