Provides Disk Defragmentation Capabilities.
New to Windows 7, this service is now used to defragment disks on a schedule. It will start and stop automatically and is not started at boot time. If you decide to disable this service (you use a different defragmenting application or use SSD), you should also disable or delete the scheduled task:
Head to Start -> Control Panel -> System and Security -> Administrator Tools -> Task Scheduler
Left hand column: Task Scheduler Library -> Microsoft -> Windows -> Defrag -> Right Click ScheduleDefrag (under Name-Status-Triggers) and select Disable (what I would recommend doing) or “Delete” (not a good idea if you wish to restore this scheduled task later).
It has been reported via email that the Disk Defragmenter service is required if you want to shrink a partition. In that case, they had a whole-drive C partition that they wanted to shrink to create a D partition, and it wouldn’t work until they turned Disk Defragmenter back on. Scheduled task, not required.
