Hi, there might be some other thing that might be stuck when you are trying to uninstall NVDA or whatever it is.  I had this happen when I tried to uninstall NVDA 2019 when my windows 7 was about to bite the dust. I was getting rid of things on there.  When I tried to uninstall NVDA. There were error messages. Don’t ask me what it was. I’ll make it up. It was something like 8554something something. I told the tec person at the source where I got this ten box. He knew what the errors were. He did fix something in the windows bios or some place.  He thanked me for telling him the error messages.  He did scrub the hard drive and recycled it.
