Settings > Accounts... clicking on Sign In Options does nothing
Title says it all. Even used @Brink 's reg patch to enable "Sign in options".
Everything else in the Settings > Accounts page, works.
IF I click on Sign In Options... it locks up just the Accounts page.
SFC and Dism /Online /Cleanup-Image /RestoreHealth... come up clean.
Even went back two backups, to June 1st (so it's not the two June updates)
