Can't start defrag in safe mode (Windows 7 Ultimate)

Defrag will run from my admin account but periodically I like to run it from Safe Mode (no networking)/Admin account .

I cannot do this on my Win 7 machine. Neither the ap display in the drive's properties menu nor can I invoke it from the CMD environment. No error messages, just doesn't start.

I'm stumped.

Unfortunately the Defragmentation tool cannot be run in Safe Mode as the service won't run in Safe Mode. It is by design.

Defragmentation used to run in safe mode for earlier version of Windows but not in Windows 7


 You would receive the following message if you try to run Disk defragmenter in Safe mode on    Windows 7.


“Windows could not start the Disk Defragmenter service on Local Computer.

Error 1084: This service cannot be started in Safe Mode”.
