AppReadiness Service and Black Screen
OffColour1972 Using Windows 10, Version 2004, Multi-Session, WVD, FSlogix, and Azure files... all users started getting this after a few weeks use of WVD. True, if I disable app readiness service and reboot the login is quick and works as expected. However, Outlook and Office issues start arising and it has to be enabled again. All updates are installed but no fix found at present. Anyone else found a fix?
Sponge405 Can you say soemthing about the Outlook and Office issues you had after disabling AppReadiness? We also want to disable the service as users are unable to work while it is enabled. We've had this problem since Windows updates from July. We have noticed that the Settings button is unresponsive when AppReadiness is disabled
MatthewHurley Basically, Outlook kept asking for the password even though it was entered and correct and wouldn't update. Our issues maybe somehow linked to MFA since we use it throughout. The solution I found earlier only works if you script it every time you login otherwise the login creeps back up and you end up waiting again. Also, by removing the reg keys you end up removing downloaded apps from the store or causing other issues.
Sponge405 Thanks for your reply. I already noticed on the second login that Office 365 SSO doesn't work when the App readiness service is disabled.
We have this issue on a provisioned Windows 2019 RDP server but the symptoms are the same: blackscreens which take anything up to 15 minutes and when you do get a desktop then the start button and search are unresponsive. CRTL-ALT-DELETE works but you can't get a desktop. Disabling App readiness removes the black screen problem but leads to other issues as I mentioned before. One of the consequences of disabling App readiness is that the settings button is also unresponsive.
It's definately related to App readiness so I'm going to play around with the registry keys and see if I can pinpoint the one causing the issue.
BTW, we have the problem with black screens since Windows Updates of July 2020, although Office 365 also got it's half yearly update at the same time. In the meantime we're being forced to use an older image so that people can, you know, actually work. 😞
Sponge405 We reboot our VMs daily to save cost and still have the issue. But, since we know "App Readiness" is part of the problem. I ran a performance test on a VM and rebooted. The test linked Skype to using a lot of CPU and time on loading, even though we don't use it or even login to it. I downloaded Autoruns and stopped One Drive (since we don't use or login to that either) and Skype from loading at start up and from loading browser extensions just to be sure. I then rebooted the VM and the desktop appeared after a black screen for approx. 10 seconds rather than 1-3 minutes. I am not sure why this would affect app readiness unless it skips trying to configure registry keys etc. on start up for one drive and skype. Now I need to try and implement on mass.
