Prefetch problem

Maybe this applies:
http://www.extremetech.com/article2/...1153282,00.asp
<snip> Point of clarification - forum member MURDOCDV reminded us that
the Task Scheduler is used in auto-tuning operations - it assists in the
creation of prefetch information for prefetching disk-resident code and
data (as we alluded earlier), so it's NOT a good idea to disable the
Task Scheduler. Thanks MURDOCDV!

Hey Superman;
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.
As has been mentioned, 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\Contro l\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 entering the command (in the command
prompt window):
defrag c: -boot | Enter
Open regedit and navigate to:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Dfrg\BootOpt imizeFunction
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\BootOpt imizeFunction
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.

Hope this helps. Let us know.

I just completed the Windows automatic update. Now when I
turn the computer on I get a pop up window telling me
that "there is no disk in the drive. please insert a disk
into drive F:" and at the top of the pop up it
lists "qttask.exe - no disk" This is new since the update
I installed today. I searched for the file and
found "qttask.exe - 18761A1A1.pf" which is in a prefetch
folder in Windows. What is going on?

Try re-installing Quicktime:

Or better yet - eliminating the registry entry that tells qttask.exe when
you startup each time - I have found NO use for it.
