windows security update KB5039211 erased apps in my registry

rachrobin  Unfortunately restore didn't save me.  I am doing a reset as I write this.  I found out later that more was wrong with my computer than I initially realized.  It was almost as if the update turned me into a new user.  All the passwords were forgotten.  I suspect that something else may have contributed to this.  I have multiple computers and although I keep trying to keep them off the cloud I don't think I succeeded.  I had to dispose of one of those computers so I tried to delete the passwords on that one so no one would be able to steal the passwords from the stolen computer.  I wonder if that caused my other computer to lose passwords when the upgrade took place.
