Using the standard Windows 7 Disk Defragmenter, does the defragmenting process continue if I close the window after star a task manually?

There's no warning when I close the window, but I always wondered if it actually continues or not.

Yes, you can close the window and the defragmentation process will continue in the background, thanks to the Disk Defragmenter service (defragsvc).

If you want, you can use Resource Monitor to make sure it's still running. Go to the Disk tab and you should see svchost.exe (defragsvc) in the list. Select the checkbox in front of it and you'll see exactly which files it's currently defragmenting in the Disk Activity list.

Indeed, in Windows 7, the Disk Defragmenter window is more of a view on the service and its schedule, than the actual program doing the task. It's only controlling the service running in background. – Gnoupi Apr 17 '12 at 14:18
Ahah! Also, easy way to check is to reopen the app after closing it...didn't think of that, but sure enough it shows that it is in fact running. – Ben Brocka Apr 17 '12 at 14:20
@BenBrocka Yes, that'll also work. – Indrek Apr 17 '12 at 14:21
