Windows 365 Remote Desktop Shows Only a Black Screen? Here’s the Quick Fix

Sometimes when connecting to a Windows 365 Cloud PC using windows App, the session connects successfully—but all you see is a black screen. You may try refreshing, reconnecting, or waiting for several minutes, but the screen remains blank.

This is a known and occasionally encountered issue, and thankfully, the fix is simple.

What Doesn’t Work

• Refreshing the session
• Disconnecting and reconnecting
• Waiting for the screen to load

If none of these resolve the issue, the Cloud PC itself likely needs a restart.

✅ The Fix: Restart the Windows 365 Cloud PC

1. Open the Windows App (Windows 365 app).
2. Locate your available Windows 365 Cloud PC.
3. Click the three dots (⋮) next to the Cloud PC.
4. Select Restart.

The restart process may take a few minutes. Once completed, reconnect to the Cloud PC—you should now be able to log in normally without the black screen.

What If You Don’t See the Restart Option?

In some locked-down or restricted environments, the restart option may not be visible to end users. In this case:

• Contact your IT support team
• They can restart the Cloud PC from the Intune Admin Center → Windows 365 blade

After IT performs the restart, the Cloud PC should work fine.

Final Thoughts

A black screen on Windows 365 can be frustrating, but it’s usually not a serious issue. A simple Cloud PC restart resolves it in most cases. If you’re restricted from restarting it yourself, your IT team can handle it quickly through Intune.

Windows 365: Fixing Microsoft Teams performance issue

Fixing Microsoft Teams Performance Issues in Windows 365

Microsoft Teams is a critical collaboration tool for many organizations. However, ensuring optimal performance on Windows 365 Cloud PCs or Azure Virtual Desktop (AVD) environments often requires specific configurations. This article provides a step-by-step guide to verify and enable Teams SlimCore Media Optimization for improved performance.

Step 1: Verify Teams Media Optimization Type

Before making any configuration changes, verify that your Teams client is using the new SlimCore Media Optimization architecture. Follow these steps:

1. Open the Microsoft Teams client.
2. Click on the ellipsis (...) on the top bar.
3. Navigate to Settings > About.
4. Check the optimization type listed under the Teams version:
   • AVD SlimCore Media Optimized: means it’s new optimization based on SlimCore.
   • AVD Media Optimized: means it’s  Legacy optimization based on WebRTC.

Step 2: Enable Teams Media Optimization

To enable media optimization for Teams in Windows 365 or AVD environments, configure a registry key on each session host if it’s not already present. This key will be present if it’s already optimised. If not, you need to configure.

Registry Configuration Steps:

1. Open Registry Editor as an administrator.
2. Navigate to the following path:

   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Teams
   

3. If the Teams key doesn't exist, create it.
4. Add the following value:
• Name: IsWVDEnvironment
• Type: DWORD
• Value: 1

Alternatively, you can automate this process using a PowerShell script.

You can find the Powershell script in my GitHub Repository 

If Teams is not optimised, you can see a Not optimised banner at top of the Teams. You can click it and select optimise virtual desktop and restart and Teams should be automatically optimised for media audio and video quality inside windows 365.

Windows 365 - Fix Microsoft Teams error code 2000

 

Recently I started to see Microsoft Teams showing Not Optimised banner at the top of the Teams. When clicked on it, it showed to optimize and restart. But when clicked on it, it started to show Error Code 2000. 

Checked in settings and it shows AVD slimcore media Not connected.

The error code 2000 means optimization is not enabled.

Tried to follow the steps outlined in my previous blog https://app2pack.blogspot.com/2025/02/MicrosoftTeams-Performances-Windows.html but it didn’t help. 

Followed the steps mentioned in the official MS article but it also didn’t work. Tried to force quit Teams manually and launch and still it was showing the same error and not optimized banner.

Finally Tried to restart the Windows 365 cloud pc from Windows App and this time after the restart and when clicked on Not optimized banner, it automatically optimized and prompted me to restart the Teams twice. After restarting Teams twice, the banner disappeared.
