Win7 does a basic defrag (not the same as a manual run), when the system's been idol for over 15-20 minutes. If enabled, a windows defender scan runs prior to that. This defrag is good enough to keep a basic system going good, but for daws you should still run the full manual defrag on all drives at least every 2 weeks.

I'm using MSE. I used to use jkdfrag and c clean on xp. So are peeps using any tools like that under win 7? I believe win 7 does it's own defrag, so one like jkdfrag isn't so needed. Any Suggestions, be appreciated. Ross.
