Disk Defragmenter cannot start because scheduler service is not running

Julian2010 · Jul 27, 2010

I would use some help, people, tried but failed lots of things.
Lately a found I could not use Disk Defragmenter, not even a 3Th party like
WinOptimizers. I turn something off, but can't figure out what.
Windows 7 64 bit
---------------------------------------------------------------------------
"Disk Defragmenter cannot start because scheduler service is not running
Start the task scheduler service and try again"

I go to Windows Task Manager->Services to task scheduler line rightClick to Start Service
and I get this, "The operation could not be completed. Access is denied".
----------------------------------------------------------------------------
Then tried on some other services lets start them but won't let me stop them again????.

Have you tried to type (services.msc) without quotes , in the search box and turn it on that way?

WCCobra · Jul 27, 2010

Follow what kvic said, and make sure the Task Scheduler service running.

Hi, task scheduler need to be in "automatic".
The change button in task scheduler in "services.msc" is "grey" out as such unable to change.
You need to go to registry to change it.
Just copy the below into notepad and change the extension to .reg and merge into registry.
Hope this helps.

yes I've done it but all options are grayout.
but not all services, just the one I want.
I login as administrator!!!
It's frustrating, dammthing.
Thanks kvic/WCCobra

Hi look what. "Cannot import <>.reg, file is not a registry script.
You can only import biary files from within the registry editor."
And inside registry Editor "Cannot Import note.reg:The key selected is invalid".
Thanks for the trouble KotaXor.

KotaXor · Jul 28, 2010

There is a slight typo error....there should be no space "Services".
Don't know why I am unable to edit my previous post though.

Also make sure The Event Log Service is running.

Julian2010 · Aug 1, 2010

I very much appreciate your help mates, but no longer needed.
You see I had a mayor computer failure, Ethernet card(on motherboard)
video card.Fixed them. Install O/S again(VAZ loader is great¡¡).
And now all runs O.K.(I'll do a System Image this time).
Thanks again. Julian.
