AppReadiness Service and Black Screen
left out change it to automatic as a work around. but they update may fix it Steven Blatt
Steven Blatt Hi Steven, thanks for the tip. The machine is already fully updated and we still have the same issues.
Robert_Greenlee It's been a few weeks now and we haven't had this issue since installing the updates mentioned
- So to resolve the issue you reboot twice a day, or are you just saying due to user levels you tend to see vm’s rebooting multiple times a day. I currently use a script to shutdown vms with no logged on users leaving an amount of available seats. Is this the same as your environment.
Our work Around was to set the AppReadiness service to Automatic. The default in Manual and we reboot 2 times a day. we see 50-60 users a day. Put a case in with Microsoft. We did. StevenR
Hi, I have just deployed wvd a month ago and was working fine up untill yesterday and now I am getting increasing black screens. What were the updates that you are referring to. my wvd is win 10 multi.
I have deployed a nigh on identical one a week earlier than this one and they are not seeing these issues. the only main difference is the problematic one users log in/out all day while the other they log in do 8 hrs and servers shutdown at night and same again the next.
MatthewHurley Over the past month there have been two patches pushed in the cumulative updates addressing the Black Screen issue. Most likely those will be the fix. Crossing our fingers. We are in production and have not seen it for the past 3 days.
ausumACR I updated our gold image this week and released it to a test VM today. So far I've been able to log on to the vm 4 times without seeing a black screen.
Here are the changes I made:
I installed the Windows Updates from September 2020 (KB890830, KB4570333 and KB4570332). I uninstalled the Client UI for App-V and disabled the Microsoft App-V Client service as we don't use it anymore. I also disabled the Citrix Workspace Updater service.
Until now we have been using Windows Defender for AntiVirus but we are currently migrating to SentinelOne. I installed the SentinelOne agent which also disables Windows Defender. We were using Sophos Endpoint protection on the file server where the FSLogix profiles are stored. Last week we removed Sophos and installed SentinelOne on the file server. Maybe this has something to do with it. As we are a 24 hour organization, users need access to the file server 24/7 so we don't manage to install Windows updates on the file server as regularly as we would like. We have to schedule a window to install updates on the file server so we took this opportunity to update and reboot the file server.
Any one (or none) of things could have caused the improvement.
I still don't trust it so I'm not ready to release it to our users yet, but if anybody else wants to try any of the suggestions let me know how it works out. I will try later in the week or the start of next week if the improvements are still there (don't want to have the virusscanner migration muddying the waters) and then post my results
We are experiencing the exact same problem. Black screens after login which disappear when we kill the app readiness process. We have opened a support case with Microsoft without any luck so far.
