The last 2 versions are taking forever just to wipe MFT Free space EVENTHOUGH I unchecked that option. I now have Windows 10. Could that be the problem?
There's issues with Win10 as made evident by so many posts on the forum, mostly with the Edge browser cleaning.
However; you really shouldn't be using Wipe Free Space and Wipe MFT Free Space so much. All of that secure deletion stuff can be left off and ran only when you want to sell off a computer. It's also possible that an installed real-time protection anti-malware/anti-virus could slow down the process since they will scan everything.
For clarification, if you're using Drive Wiper then you will get a wipe MFT whatever is checked in Options/Settings.
