  • I recently upgraded from Windows 8.1. The first thing I did after upgrading was to check the Settings app in the Start Button, instantly after clicking the app it instantly crashes, tried restarting my PC even shutting it down for half day and still no luck. So I seriously need help with this because Windows put ever important components there such as Windows Update (How can I patch updates if I can’t access it) and even Recovery Option (How am I suppose to downgrade without losing my files). I’m having no luck here, so please anyone can you me?
