Hi! Roughly since I updated Windows on April 11th I've been having issues with my mouse not working and programs freezing. The mouse won't click on anything unless I hit ctrl alt delete, then it will work again anywhere from one click to several minutes before freezing up again. It also right-clicks a lot even when I'm not touching the computer whatsoever, and it clicks on things I am not even using. It's making it virtually impossible for me to use my computer. I've tried an external mouse, the trackpad, AND my friend remote-accessed my computer via teamviewer and it did the same thing for him. I uninstalled all the mouse drivers and reinstalled them. I'm pretty sure this is not a hardware issue.
My next attempt was going to be to reinstall Windows, but then I discovered I have a password error. I use a PIN to log into Windows, and I use my Microsoft account to log into OneDrive, Skype, etc. When I rebooted my computer in safe mode (I think?) and went to the option to reinstall windows but save my personal files, it asked for my password. However, neither my MS account password nor my pin work. I even tried resetting the password. I can log into all my Microsoft accounts fine. So then I went to Users and tried to remove the PIN to log in to my Windows account locally, but it asked for my MS password and there it says it's incorrect, too. I have tried calling Microsoft 3 times to deal with this issue but keep getting disconnected. I finally gave up after 4.5 hours of attempting to reach them yesterday, and today they are closed.
Please help, I am traveling and I work online and I desperately need to use my computer, but I don't know how to fix this. Thank you!
