The registry entry for the prefetch folder may be set wrong. If you
feel comfortable about getting into the registry, do this:
Click Start, Run, type in "regedit.exe" (no quotes)
Navigate to the following key:
HKLM\System\CurrentControlSet\Control\Session Manager\Memory
Management\PrefetchParameters
Change the key "EnablePrefetcher" from 0 to 1 to turn prefetch on.
Reboot. It'll take several days for the prefetch folder to begin to
fill up with entries.

Try this one:
1. run "regedit";
2. goto
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory
Management\PrefetchParameters\EnablePrefetcher];
3. Set the value to either 0-Disable, 1-App launch prefetch, 2-Boot Prefetch, 3-Both ("3" is
recommended).
4. reboot.
It should decrease the boot time and the time it takes to load programs.
1. run "regedit";
2. goto
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory
Management\PrefetchParameters\EnablePrefetcher];
3. Set the value to either 0-Disable, 1-App launch prefetch, 2-Boot Prefetch, 3-Both ("3" is
recommended).

I've seen this problem before. For some reason if the Prefetch
folder is completed deleted (Contents), Windows Xp doesn't
want to recreate the data. I suspect this may be due to the
Layout.Ini file not being found. Even with Task Scheduler &
appropriate Registry Keys set, I worked on a PC that refused
to log .PF's and function correctly. As best as I can remember
we extracted the original Layout.ini from an image and installed.
Afterwards, the Prefetching resumed operation.
In my opinion, Prefetch is a self-maintenance utility and it's best
to leave the data/settings alone.

[I deleted the file layout.ini (in the same WINDOWS\PREFETCH directory). Then I rebooted my system
three times. This was to force the boot-related files to be re-evaluated and have their prefetch
data refreshed. I then opened a command prompt window and entered the command:
rundll32.exe advapi32.dll,ProcessIdleTasks
At this point, the file layout.ini was rebuilt.
I then forced a "boot optimization" by entering the command (in the command prompt window):
defrag c: -boot
It finished pretty fast, so I looked in the registry to see what happened:
HKEY_LOCAL_MACHINE
SOFTWARE
MICROSOFT
DFRG
BootOptimizeFunction
and the "OptimizeComplete" item was set to Yes. So I set the LcnStartLocation to zero and the
LcnEndLocation to zero, and ran the -boot again. These two fields are the logical cluster numbers1
of the beginning and ending of the boot-optimized "zone". The built-in defragmenter (and Diskeeper)
do not move files in this zone in order to honor the boot-optimization.
This time running "defrag" took longer and the LcnEndLocation was 363658, with the LcnStartLocation
being 345622. That's a range of 282MB on this volume.]

I had a problem with Prefetch not recreating the Layout.ini. I followed the steps above and it was
recreated.
