disk defragmenter cannot start becuase the task scheduler service is not running. Start the task scheduler service and try again


windows 7 ultimate 64-bit
anyone know the fix ?

Did you try going into Services and starting Task Scheduler?

Press Winkey+R, type services.msc and press Enter or click GO.
Scroll down to Task Scheduler and double click on it.
Set the Startup type to Automatic then click on the Start button.

You're welcome. Did it work?

Hi, I'm having the exact same problem but when I follow your steps it says "The task scheduler service on Local Computer started and then stopped. Some services stop automatically if they are not in use by other services or programs." Also, when i go to Properties, the menu that says "manual" is grayed out, so I can't change it to automatic. It was working fine a few weeks ago.

 

[Ztruker]

Task Scheduler being set to Manual should be okay. Manual means it will start if needed, though you should be able to change it. Is your account an Administrator?

 

[AlucardAlive]

Yes, the account is admin (as it's the only account on the computer) but it is still grayed out and I still can't turn Task Scheduler on.

I found one post that hag a .reg file for Vista. Compared it to the same area for Win 7 and they did not match so I exported

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Schedule]

You can compare it to yours or just download it, unzip it and merge it into your registry. Would be a good idea to either create a System Restore point first or backup the registry using ERUNT or export the key before merging.

This is the .reg file (zipped): View attachment scheduler7.zip

I backed up my registry then merged the .reg file and rebooted my computer but the only thing that seems to have changed is that the grayed out drop down menu says Automatic instead of Manual now (which is weird because it still isn't starting). I think I just might do a fresh reboot of Windows once I can back up my files because this isn't the only weird problem I've been having recently.. Thanks a lot for all your help!!

I am also having the same problem. Unable to run task scheduler in Windows 7 Ultimate. When I type regedit, an error message pop-up stating "The endpoint mapper database entry could not be created" even though I looged in as Administrator

Could be malware/virus?

 

[Ztruker]

Lots of cases of other people having the same error but I did not see a single instance in which a fix was provided. All did a new install. You could try the Repair option from System Recovery Options.

How to Run a Startup Repair in Windows 7

From that same menu you could try a System Restore or open a Command Prompt and run sfc /scannow.

Thanks for the comments. Re-format and re-installed Win7 and it worked properly. Should have done it in the first instance. Suspect it may have been from the third party driver providers when I was looking for my broadcom wireless card driver; even though I did not download their drivers but just stopped when they wanted to charge to download their driver. Later found out that the wireless driver was in the windows update.
Lesson learnt is after installing the Win7 OS to download all the Windows updates and install them before installing other programs.

Then create an image backup so if anything goes wrong it's simple to recover.

One thing that could keep you from doing defragment is your Administrator account doesn't have all privileges/permissions that you think it must have. Or even Administrators group hasn't been added to security list of the executable file you are trying to open (defrag.exe).

The following will help:
Open Computer -> right click on disk C: -> click properties ->hit security tab ->hit edit-> hit add-> hit advanced-> hit find now -> find your login name in the list you might add Administrator and Administrators as well -> hit ok-> hit ok-> find your name in the security list click on it and check allow on all permissions.

You need a "Defrag" folder in Task Scheduler

I deleted the "Defrag" folder in Task Scheduler because I only want to run Disk Defragment manually. However, Disk Defragment can only run if there is a "Defrag" folder in Task Scheduler. If you need to put it back, run Task Scheduler, go to Task Scheduler Library, Microsoft, Windows. If there is no "Defrag" folder, click New Folder, and add a "Defrag" folder. Then reboot and try to run Disk Defragment.

Solved task scheduler service cannot start local computer

To solve this
go to services
win+r and type services.msc
go to task scheduler and see if its stopped
than go to windows event log service and change its start up type to automatic, than click on start service
now go back to task scheduler service and change its start up type to automatic, than click on start service
and it will be solved
