Are you telling me you don't have a second backup admin capable account?
I have run into folk that run with just one admin account and eventually the old CORRUPT PROFILE bug bites and they are now in a recovery position.
Also, what about safe mode boots? You didn't tell.
-> Here's the thing. Windows is still a technical OS. It's not user friendly and certainly can't be used without backups and installing some safety nets (that second admin account.) This has caused more than a few to go buy an Apple.
Ever since an update on 09/22/2016, my fingerprint reader has been locked out. I get a message saying, "Group Policy Client Service", and some other info about not being able to log on as administrator.
I have tried NUMEROUS fixes. My first problem, is that I am unable to get into the command prompt, under (admin). I can get into the command prompt regularly, but not as an administrator. I was trying to get in, so I could do a "netsh" and then "winsock reset".
After that failed, I tried getting into my system settings and clicking on system protection, but after 5 minutes of waiting, I get a message that says it's taking too long, and it can't open the program.
In addition to all of this, I have also seemed to have lost the ability to get into Task Manager.
I hope someone has some insight, and can help here. I am sure there are a few other things going on, but Microsoft, as always, is useless in this problem. Even though, I believe they have created it.
