So I wan looking at the Computer Management program thing today. So I decided to look at the Disk Management tab. For some reason I have 20.95 GB of free space. (picture) I decided I would just delete and get all that space back. Well, I can't I always get an error (picture). Can anybody help? Thanks, Nothinbeter2do
Try downloading CCleaner. That should help. On the Advanced tab of the Cleaner section, make sure you put a checkmark on the "Wipe Free Space" option.
I fixed it. The thing is... I fixed it using Ubuntu. The REAL reason I had 20.95GB of free space is because I was uninstalling Ubuntu. Kinda contradictory.
