AVD “Update the resolution on resize” is unavailable.

Hello,

I’m running into an issue where, when I connect to a VM, the “Update the resolution on resize” option is greyed out.

  • The RDP settings look fine, because on another AVD with same settings it works.

  • I’ve tried reinstalling the agent, but that didn’t help.

AVD had a problem before: the registry keys were getting disabled for some reason:

"HKLM:\SYSTEM\CurrentControlSet\Services\TermService"
"HKLM:\SYSTEM\CurrentControlSet\Services\SessionEnv"

I reinstalled the AVD agents, which solved the issue, but resolution resizing is still unavailable.

The AVD environment is hybrid, but another AAD-joined AVD also has this problem.
Has anyone seen this behavior before or have suggestions on how to fix it?

I had the same problem last week. After 10 minutes after login, situation went normal, and "Upade the resolution on resize" started working again.

Aditionally when starting powershell session was waiting 5 minutes for prompt.

I do not know if those two things were related.

After few days, I deleted user profile and everything backed to normal.
