Cant enable prefetch, registry value Enableprefetcher resets to 0 after reboot
Posted on 2004-08-20
What to do if the registry wont remember my registry value for EnablePrefetcher?
It's set to 0 from the beginning, and after I change it to 2 (or 1)it will reset to 0 after the next boot !!??
The problem is that I want to enable prefetch on my laptop (Thinkpad A31p),
I change the "Enableprefetcher" value from 0 to 2 in
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Session Manager\Memory Management\PrefetchParameters
But after each reboot the value is set to 0 again.
Once I set the value to 2 the computer prefetches as it should and the boot time is about 50 sec. But if I dont change the value again before rebooting the next boot will take about 5min.
I have noticed that if I open the registry and check the Enableprefetcher value before ZAP and NAV loads, the value is correct, but after windows finish the value is set to 0 again. I tried to disable ZAP and NAV, figguring that this would solve the problem but it didnt.
So the problem is that for some reason the registry loses the settings or another application is resetting it after each reboot. What to do?
I have checked for spyware, virus, browser hijacks etc. and cleaned the Prefetch folder.
I really need some help on this...
