Okay from the location Windows was using your C:\ drive for User files, and on its own Windows didn't place anything on D:
I suggested you create another user, with admin rights so you could delete your current user and all hidden files associated with it.
Windows stores a lot of stuff down the hidden AppData path c:\users\dense\appdata. This is a hidden folder. Things like profiles and even Outlook 2016 mail can be found down this path. I wanted all this space to be marked free so CC Cleaner would overwrite.
Seven passes is way more than you need. One would kill it for most people to be able to recover. Three and you would likely need NSA resources.
Your boot drive, the one that contains Windows is C:. You will see this in your disk management shot. In brackets it says boot)
So you could use CC Cleaner to wipe free space on C:. As it is a third of the size it won't take as long.
You handle the Appdata path anyway you wish, I gave you my way of handling by deleting the Dense user.
The two little partition on Disk 1, 100MB and 500MB do not contain any data. The 100MB tells the systems where to find windows and the 500MB is a recovery partition so you can boot and "Fix" things.
Hope this helps.
