Disk Defragmenter - cannot start... task scheduler service not running

[M W]

I went to open up Disk Defragmenter today and it gave me this error:

"Disk Defragmenter cannot start because the task scheduler service is not running. Start the task scheduler service and try again."

I went into services.msc and Task Scheduler was already running. I thought about restarting the service but the option is greyed out. I rebooted my PC several times and opened the Task Scheduler program, but neither helped.

This is definitely a first, I usually defragment about once a month...

Any help would be appreciated. Thanks!

Check to make sure your windows event log is also not disabled in services and then run System File Checker.

I ran Windows Update last night and now it's somehow working again.

Not gonna question it.

Yup that's how pending updates seem to work most of the time, glad you got it sorted.
