Seems a little harsh no? :)

Just carrying forward the tone of the post I was replying to.

 

I replied to the original post with a little education about who we are, and what is the purpose of these forums. I gave the benefit of the doubt that the person was just googling around for similar situations, and posted here thinking we were a general tech support area.

 

The reply was less than cordial and did not address my question at all, so I replied in kind.

Maybe some other Unraid users might appreciate the given background info.

Yes, I've found this thread via Google and took the time to register as a new user in order to help you guys. I've only worked with XenServer, Freenas/bhyve, VMware and Hyper-V so far. No experience with Unraid yet. The issue discovered by the OP is not related to Unraid, Hyper-V or any other hypervisor. It's just another bug in Windows 10 1903. So sorry for answering the OPs question. Goodbye.

I'm sorry I didn't see your post for what it was, a genuine effort to help.

 

Most of the time when a first time poster jumps in to a thread with a bunch of links to external websites, it's a spammer, only out to further their own agenda.

When you declined to answer any of my questions and instead got defensive, I took that as confirmation of your intent to help yourself instead of helping others.

Maybe the wall of links given in my first post might be a bit long winded. I'll try to sum up the info:

 

Windows 10 1903 introduces a new display driver for remote desktop sessions (WDDM based Indirect Display Driver - IDD). As soon as a rdp session gets disconnected (i.e. the user is still logged in, but the rdp session is disconnected) the new driver causes the Desktop Window Manager (dwm.exe) to max out one cpu core.

 

Until Microsoft comes up with a proper fix/update, the following workarounds are known so far:

 

- Revert back to Windows 10 1809

 

- Switch off the new driver by disabling the following Group Policy: "Use WDDM graphics display driver for Remote Desktop Connections" in "Computer Configuration\Policies\Windows Settings\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Remote Session Environment\"

This Group Policy was introduced in Windows 10 1903. Configure it either locally via Group Policy Editor gpedit.msc or as a domain wide group policy object in Active Directory.

The new Indirect Display Driver is related to another RDP issue in Windows 10 1903 as well: RDP showing a black screen when trying to establish a session.

 

Because I don't wanna hijack this thread with possibly unrelated workarounds, I'm looking forward to feedback from affected users, first of all the OP.

This is what I used and appears to solve the problem for now.

Just found that I had the same issue with both of my Windows 10 VM's. Changed the GPO setting as suggested and this resolved the issue after a reboot. Thank you for your suggestion.
