AppReadiness Service and Black Screen
Jason Fritz Thanks for these, I've applied them so that the we don't get stuck at the black screen, however I've found that the App Readiness service still causes other problems.
For our users they still have issues with anything requiring Modern Authentication to O365/Azure and Outlook stops connecting. I also have a case with MS but I can't get any info on the real fix and I also ended up discovering the Windows Search bug and another issue with FSLogix not correctly disconnecting VHD files correctly.
Lee_E Hi I wont take credit for this as I was handed this by MS
Also please create the following Reg Key on all session hosts and set Value to " 1 " after you upgrade to FSLogix 2009:
CleanupInvalidSessions
SET IN: HKLM\Software\FSLogix\apps\CleanupInvalidSessions
Available in FSLogix release 2009 or later
Type: DWORD
Default Value 1
At times a Windows Session may suffer an inelegant termination, in these cases FSLogix is not provided an appropriate event to trigger the dismount of the VHD(x) file for Profile Container and Office Container. By setting CleanupInvalidSessions to 1, additional FSLogix logic is triggered to make this scenario less likely. Setting CleanupInvalidSessions will cause the functionality to be utilized for both Profile Container and Office Container. KNOWN ISSUE: at this time CleanupInvalidSessions should not be used in conjunction with Cloud Cache when concurrent sessions (e.g utilizing ProfileType/VHDAccessMode) are in use.
