I was preparing to create a system image and rebooted Windows 10 21H2 before proceeding. Once it had booted it would not accept my PIN and there was no option to enter my password. In the advanced options I tried to restore from a restore point and discovered that there were about 70 restore points all created by Windows Module Installer. Restoring from them failed. I tried to rollback feature updates and system updates also failed. Microsoft Authenticator was of no help, so I’m about to do a reinstall and keep my stuff.
What was Windows Module Installer doing?
Anybody know why this has happened and how to avoid it in the future?
