I left for vacation for two weeks and on getting back, my desktop seems completely FUBAR.
I have a few issues that I think are connected:
1) I cannot connect to any HTTPS site in either Chrome or Microsoft Edge. I can however connect to non-HTTPS sites.
2) Whenever I try to run the Microsoft troubleshooter I get an error that says "Validating the integrity of the troubleshooter failed."
3) I thought the problem might stem from having a VPN installed on the computer so I tried to uninstall my copy of ExpressVPN and I get an error inside the ExpressVPN installer that says "Fatal error during installation."
4) I can't update Windows10. The last time it checked for updates was 9/4/19
Can someone please help me figure out what is going on? I have tried various things to fix the individual problems (changing date/time settings, flushing DNS, changing DNS server, etc.)
