[Update] Disruption: Research Cloud - Windows-Server-2025

Tuesday, 09 June 2026 09:19:00

Research Cloud

Resolved after 5h 47m Tuesday, 09 June 2026 15:06:00

[Update] A workaround is listed below.

Currently, it is not possible to provision functional Windows Server 2025 VMs in the Research Cloud. Connections via Remote Desktop (RDP) or VMware Remote Console (VMRC) simply result in a black screen.

Until the issue is resolved, the Windows Server 2025 templates have been temporarily removed from the provisioning menu.

Thank you for your understanding.


Workaround: As of now, this is a Microsoft-related issue. A fix is expected to be released shortly via a Microsoft update.

The following workaround can be applied to affected systems. We are working on our VM deployment process so that this workaround will be applied automatically in the future. Workaround:

  1. Connect to the affected VM via the Emergency Console (VMRC) in the Self-Service Portal.

  2. Open Task Manager (e.g., using Ctrl + Shift + Esc).

  3. Click “Run new task.”

  4. Type “powershell.exe” and press Enter to launch PowerShell.

  5. Run the following commands one after the other:

Add-AppxPackage -Register -Path ‘C:\Windows\SystemApps\MicrosoftWindows.Client. CBS_cw5n1h2txyewy\appxmanifest.xml’ -DisableDevelopmentMode

Add-AppxPackage -Register -Path ‘C:\Windows\SystemApps\Microsoft.UI.Xaml.CBS_8wekyb3d8bbwe\appxmanifest.xml’ -DisableDevelopmentMode

Add-AppxPackage -Register -Path ‘C:\Windows\SystemApps\MicrosoftWindows.Client.Core_cw5n1h2txyewy\appxmanifest.xml’ -DisableDevelopmentMode

Then restart the operating system.

After the restart, you should be able to log in via Remote Desktop again without the black screen.
