Trying to crash the other threads for debugging purposes....

Your Prefetchfiles are outdated. (Program hints)
But the crash is not normal. The bug is known and will be fixed in the next version.

1. Delete all files in your Windows\Prefetch folder.

2. Most likely cause is that the task sheduler service is disabled. Please enable it and try following command with administrative rights:

rundll32 advapi32,ProcessIdleTasks

3. If you use Vista or Windows 7, you have to do 5 reboots. It will create a boot trace. If not, please skip this step

4. Now MyDefrag won't crash anymore and it will use the created layout.ini file and the program hints to lay out the files for faster startup of Windows and Applications.

Thank you. Your suggestions seemed to have solved the problem. I was able to rerun and complete the system defrag without a crash.

Thanks again

Yep, I just got that problem as well. Thanks!

2. Most likely cause is that the task sheduler service is disabled. Please enable it and try following command with administrative rights:

No it isn't.

rundll32 advapi32,ProcessIdleTasks

This works for XP only apparently.

3. If you use Vista or Windows 7, you have to do 5 reboots. It will create a boot trace. If not, please skip this step

No it doesn't.

So far so good except in W7 x64 the prefetch stays stubbornly empty after wasting an hour on reboots. There's probably some event that will repopulate it eventually. Just apparently not one of those "idle events". Once a week defrag at least will not run if you are looking ie computer is not idle.

Is the Superfetch service enabled?

[Barleyman]

Is the Superfetch service enabled?

It WAS disabled but I re-enabled it when I looked into this thread 1st time when I had the crash with mydefrag. I'm not sure if it's that beneficial feature on a games box with lots of memory, I just tested if turning it off made any difference either way, which it doesn't seem to.

Interestingly superfetch service was in fact not started althought it was set to "automatic". Possibly something to do with this problem. Started okay when manually run, thought.

Edit: Oh, all right. Now that I force-started superfetch, it populated the prefetch folder.

It does only something if your installation or last run of this command (it will be run automaticly) was three days ago.

3. If you use Vista or Windows 7, you have to do 5 reboots. It will create a boot trace. If not, please skip this step

No it doesn't.

Test it. Empty your prefetch dir and do some reboots and look what happens in this directory.

Perhaps the service "superfetch" is disabled. So Windows won't do a boot trace.

 Thank you so much this has been annoying me for the last week and so had to run Defraggler. It is so nice to have a properly constructed program doing the work again.

 I better say I am using Win 7 Pro (64 bit), all I had to do was check that superfetch was auto, checked task scheduler also then deleted everything in prefetch, restarted 5 times. Bingo bango Bob's your Aunty.

See When are you releasing your next version?

[Fergler]

MyDefrag was crashing for me as well, but BloodySword's reply solved my problem. Thanks!

[Mailduin]

Dear Bloody,

I have an older computer and had to wait untill all services were started. Defrag was OK then.

Thanks for the help
