Welcome to Justanswer.com, my name is ***** ***** I will do my best to assist you.
We may be able to handle this without remote support and keep your costs lower. Since you mentioned you can get to the point where you can attempt to download programs or exe files.. I assume you can boot into windows.
So lets try these steps first and let me know what happens
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.
I strive to provide great service, and greatly appreciate a 5 star rating clicked and submitted when you are satisfied.. I always answer follow up questions.Dustin S.Senior Technician and Network Switching Systems Operator / Maintainer.
