Anyone else seeing problems with black screen at login for 5min? All my digging has pointed to the AppReadiness service and possibly corrupted fslogix profile disk. Event logs show an NTFS disk check running on the profile disk, which probably causes a timing issue with AppReadiness. Eventually, the desktop appears but the start menu does not work. Task manager shows a runaway Push notification that is consuming excessive RAM (20+GB and growing). Killing the runaway process allows the left click start menu to start working (eventually) but GPOs have not applied properly so users have other probelms.
The only thing I have found that seems to fix this is to delete and have a new user profile created.
