Can't defrag, Task Scheduler not started

I am running Windows 7 (upgrade from Vista). When I try to run defrag on my harddrive I get an error message saying it can't because the Task Scheduler service is not started. When I check, the service is started and set to start automatically. Why am I getting that message?

Hi,
I would like suggest you running the System File Checker (SFC.exe) using the /Scannow parameter helps.
How to use the System File Checker tool to troubleshoot missing or corrupted system files on Windows Vista or on Windows 7:

Spencer - Thanks for the reply. I had run SFC before and got no violations and just ran it again, and again had no violations. I also discovered there is no Defrag task in Scheduled Tasks. Shouldn't there be? If there should be one, how do I resurrect it?

Hi,
What's the type of your hard drive? Is it a SSD? If yes, you would not use Defrag function. The defrag function can only be supported in Windows 8.
Regards.
Spencer

Hello again Spencer. The hard drive is a Seagate ST9320320AS which is SATA. I think I have solved my problem though. I right clicked on the C: drive and selected Properties\Tools\Disk Defragmenter and was able to run Defrag manually. I was also able to reinstate the Defrag task in Task Scheduler using the Configure Schedule option. I can't believe I never thought to go that route in the first place. Oh well, I always try the most difficult way first not the easiest.
