Azure Virtual Desktop - Black Screens on logins - What we've tried so far
TLDR - Azure Virtual Desktop Black Screens. Could be 2 Min long, could be much longer. Tried removing stuck profiles, spun up all new VMs to see if that would fix it, finally disabled an applicatio...
Same issues here with a Windows 10 host pool. Replaced with a new Windows 11 host pool (same VM SKUs) and no issues since. Far from ideal 'solution' though, but I have found Windows 11 AVD hosts to be a lot more stable for our customers, very few issues reported from our customers using Windows 11 host pools compared to Windows 10 host pools.
Edit: To clarify, none of my hosts are enrolled in Intune. All policies set via GPO.
- Spent the night with Microsoft, finally got the hotfix off them, applied it and are error free. They are adamant in not using it in production but I don't think we have a choice, this has been a damaging few weeks for the credibility and reliability of AVD with a lot of our customers.
- What is the hotfix for? Defender? Are the Defender settings for your hosts getting applied via Intune or GPO?
- The hotfix is related to the AppX crashes -- nothing to do with Virtual Desktops at all. I think the reason it impacts VDIs more than other machines is the number of sessions logging in and logging out. It seems to be most problematic during those two phases, so it makes sense that it's more prevalent with VDIs.
Rebuilding the host pools WITHOUT applying the patch noted above did not work for us, FYI.
- Heads up as there is potential issue with defender platform update causing exclusion not to apply, and that seems to be isolated to windows 11 multi-session managed via Intune. It does potentially impact ASR but reverting the platform version seems to resolve it. All of our AVD win11 hosts are hit by this other thing now...
https://www.reddit.com/r/Intune/comments/1fp1xa0/latest_ms_defender_platform_update_broke/- Thanks for the heads up. Another dodgy update by MS! I assume this broken update has been released to the broad update channel? I would forgive MS somewhat if the broken update was only released to the pre-release or preview channel, but not the broad channel.
It does feel like the issue I was having on my old Win10 host pool with certain apps not running, black screens, lock ups etc, but I have no hosts enrolled in Intune, AVD can be bad enough without throwing Intune into the mix! All policies for my hosts (Win10 and Win11 host pools), including Defender settings, are set via GPO. - Same here( black screen and lost asr rules/exclusions from intune) both w10 and w11
