Re: Why does my shutdown menu always have an option to "update and restart?"
Feature updates can and do occasionally "burp" and result in peculiar behavior. I've had a couple of those myself, and almost invariably, if I do a repair install afterward it fixes things. If it doesn't, I then restore from my backup and try applying the update using these instructions, not the Download and Install link in Windows Update, after a couple of weeks have passed and using a freshly downloaded ISO file: Doing a Windows 10 Repair Install or Feature Update Using the Windows 10 ISO file
Notice that doing a Feature Update versus a Repair Install is exactly the same as far as the steps you follow. The only difference is a Feature Update means you're using an ISO file for a Version that's newer than what's currently running while a Repair Install uses a fresh copy of the ISO file for the same Version that's already running.
