Hello. My name is***** to JustAnswer. I'm reviewing your question now, and will post back with your reply momentarily.
Please understand, we will try different methods if needed to get your computer working again.
You can access system restore without signing in. Here is how.
Shut down the windows 10 computer, start it.. When it gets to the windows sign in screen, dont sign in.
Instead, left click the power button at the bottom right.
Then, hold down the shift key on your keyboard, and then click restart.
This should bring you to the blue screen menu.. Choose troubleshooting, advanced, and then choose system restore.
Once system restore loads, choose a restore point that was one day before this problem started and then carry out the system restore.
That should fix the issue, but if you get stuck or this doesnt work then please send a detailed reply and I will assist you further as needed.
