I could create a new document on the desktop and was able to access it.
I was able to repair one by re-pinning it. Task bar items point to C:\Users\username\AppData\Roaming\Microsoft\Internet Explorer\Quick Launch\User Pinned\TaskBar instead of the file location. My pinned task bar items were all broken, but my pinned start menu items worked. I could access folders normally, but images and text documents were all access denied.
It booted up fine, but when I got the the desktop none of the shortcuts would work and the files there were denied permission. So I gave up trying to recover the video and put the win10 HDD back into the original system. I don't know if this paragraph has anything to do with the issue, but I wanted to be thorough. A window popped up showing the progress, but it was taking forever so I force closed it. While I was on the windows 7 PC I attempted to view my user/appdata folder, for the win10 drive, which then proceeded to ask for permission which I granted. Unfortunately It was not able to recover the files. I shut down the PC, removed the hard drive, and installed it into another, Windows 7 PC, as a secondary HDD.
It all started when I accidentally, permanently deleted some video clips I didn't mean to delete.
