Azure Virtual Desktop - Black Screens on logins - What we've tried so far

Thanks for the reply dit-chris and mgorton but I was not being able to test this because today we find out that Microsoft silently pushed out more information for a possible SSO issue fix. See: https://support.microsoft.com/topic/kb5048864-avd-users-might-experience-extended-time-on-a-black-screen-during-logon-and-sso-failures-7c1bbe77-ab9c-4c9e-80b8-6d6a9a5c8c20?preview=true

They also changed it now to resolved and mention that this is the resolution on this page... https://learn.microsoft.com/en-us/windows/release-health/status-windows-10-22H2#avd-users-might-experience-extended-black-screen-during-logon-and-sso-failures

So basically they want us to create a new golden image and slipstream the preview patch https://support.microsoft.com/topic/f307a4b0-f62d-4c28-9062-44207aea55c3 and then deploy new AVD servers. 

We are now testing option 1 on our test server. Please let me know if this is working for you guys?

Option 1: Re-image the affected device

Follow these steps to create a new https://learn.microsoft.com/azure/virtual-desktop/set-up-golden-image by using the latest "Windows 10 Enterprise multi-session, Version 22H2" gallery image from the Azure Marketplace:

1. Go to the https://azuremarketplace.microsoft.com/. In the Search Marketplace search bar, type Microsoft Windows 10.
2. On the Microsoft Windows 10 page, click Get It Now.
3. Sign-in once you are prompted to enter your email address.
4. On the Create this app in Azure page, select Windows 10 Enterprise multi-session, version 22H2 from the Software plan drop-down list.
5. After selecting the image, click Create to create a new virtual machine.
6. Follow these steps on the https://learn.microsoft.com/azure/virtual-desktop/set-up-golden-image page:
1. https://learn.microsoft.com/azure/virtual-desktop/set-up-golden-image#create-an-image-from-an-azure-vm to create the custom image.
2. https://learn.microsoft.com/azure/virtual-desktop/set-up-golden-image#customize-your-vm and then install the October 24, 2024 Windows Update (https://support.microsoft.com/topic/f307a4b0-f62d-4c28-9062-44207aea55c3).
3. https://learn.microsoft.com/azure/virtual-desktop/set-up-golden-image#take-the-final-snapshot
4. https://learn.microsoft.com/azure/virtual-desktop/set-up-golden-image#run-sysprep
5. https://learn.microsoft.com/azure/virtual-desktop/set-up-golden-image#capture-the-vm
7. You can now reimage your affected AVD device by using the newly created custom image from Step 6.

​​​​​​​NOTE  If you want an image that includes the fix https://support.microsoft.com/topic/f307a4b0-f62d-4c28-9062-44207aea55c3 for this issue, you will have to wait until November 19, 2024 to reimage your device (to avoid step 6).
