I upgraded through Windows Update, and so far:
- "Exporer.exe" crashed, then crashed when I hit CTRL+ALT+DEL and I had to powercycle
- Some store apps became unavailable, and when I try to install from store they error out
- Beta store suddenly "Not available in your region"
- The whole Settings app is Right-To-Left despite my language being English! (it goes back when I change my regional time settings, but why are those even related to language?!)
- Right click with pen is dodgy at best
- Wifi module crashed when I tried connecting to my Uni. network, twice.
- Open programs crash. A lot.
- Opening any setting window not from the main screen (like "Wifi" etc.) opens smack in the middle instead of at the top
