Windows 10 start menu not working, Edge not working, Paint not working, etc.

At home, Windows 10 start menu isn't working, Edge won't open from my Taskbar, Internet Explorer is frozen, MS Paint won't open from the Task Bar, I can't open Task Mgr from Cmd nor after Pressing Ctrl-Alt-Del and then pressing Task Mgr.

This all of a sudden, really nice PC - HP Envy, I can't even get the details because Right-Click on Start --> Systems isn't working either. When I press System it just goes away.

I'm very careful, no idea what this could be and tried a couple of things with no luck.

This link seemed the best, but I can't launch task mgr so I can't run powershell with Admin privileges. I've already re-booted as well.

That is a lot not working.  Do a Windows 10 Repair Install as that should fix most of it.

Go to the Media Creation Link

Windows 10 is running, so click on the Download button (not Upgrade Button, select Open (Run) but NOT Save. Allow the program to run. Allow drivers to update. Then select Keep Everything.
