W10 H21 upgrade from W7 - Can't get past Location setting screen

So I've been carrying on this afternoon - I've tried opening another clean desktop and switch to that - nope. I can do a Win+R and so I can open an elevated cmd which comes up behind the page above or PowerShell and so I can run commands there - not sure how useful that is atm as I can't read the outputs - too small. Can also open pretty much anything but it all stays behind this page. Event log not much help. If I knew what the process was called I could stop it from starting in the first place. msconfig reboot with startup disabled - no change. Disabling things one at a time is getting really tedious. It's so incredibly frustrating I'm now considering ditching W10 altogether and going back to Linux. Just this one thing that's seriously ruining it so far.  Untill this is done I can't really run the Lenovo BIOS or driver system updates.
