My prefetch folder is no longer logging data. I've checked the registry settings and all is ok there. Has anyone ever run into this? I occasionally clear the prefetch folder as part of my system maintenance. Was there something I shouldn't have cleared? :confused:

Yes, That key entry is set to 3. To disable prefetching set it to 0. I already use Bootvis (that's actually how I noticed my prefetch didn't seem to be collecting data). I remember reading somewhere that XP only starts populating the prefetch folder after x number of reboots. Does anyone remember how many reboots that was?

If I remember correctly I once cleared mine completely and the
folder disappeared for a day or two, then returned.
Now I always leave a few files in it to keep it there. Perhaps your problem is different. :(

Hi Guys, :p

I might be a bit late in replying to this post but here is a solution that worked for me!!

To re-enable prefetch do the following:
START | RUN | SERVICES.MSC
Locate "Task Scheduler"
Double click the service "Task Scheduler"
Set to run "Automatic"
Start the Service

then:

START | RUN | CMD
enter:
Rundll32.exe advapi32.dll,ProcessIdleTasks

Also, you may want to ck your registry to see if it has been disabled.

Start > Run > regedit

Then,navigate through the left pane until you get to this hive:

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

In the right pane, look for the key named EnablePrefetcher. The value of this key represents how prefetch works on your system. Values you can choose from include:

0—Disable
1—Application Launch Prefetch
2—Boot Prefetch
3—Prefetch everything

I would recommend you use the '1' value, which is how mine is setup, but considering the amount of RAM you have, you could even push the envelope to '3'.

Another tip, once you have done the above steps run your disk defragmenter.

Hope this helps you all!! :)
