Solution To Raxco PerfectDisk Offline/Boottime Defrag Driver Confllict error

I think I have found a previously unknown solution for the above - it's caused by Windows own defragger being set to run at boot-time, which may have been set by TuneUp Utilities or some other 'Optimisation' utility.

Here's what you need to do:

Start/Run/Regedit

Locate the following registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\DfrgBootOptimizeFunction

If value is Y (enabled) change value to N to disable.

Perfectdisk should now do an Boottime/Offline defrag for you with no problems now (well it worked for me anyway!)

Fingers crossed that it works for you too!

 

Hi!

Also older ZoneAlarm antispyware, caused this problem. ZA fixed this with a new spyware engine. This drove me crazy, for awhile.
