A black screen is observed right after the RDS session login:
Windows AppReadiness service activity is stalling Desktop appearance. Possibly due to some other bug.
Confirmed to happen in User Profile Disk and WVD + FSLogix environments. Possibly not noticed in usual RDS since it is less affected.
Stop and Disable App Readiness service. Login time should improve after this change.
NOTE: App Readiness service may need to be started before installing Windows Updates that require restart.
