Repro Steps

Since installing 1.0.3.0 via wsl --update, at random times RemoteApp windows will pop up "the identity of the remote computer cannot be verified. Do you want to connect anyway? (yes/no). If the window is ignored and left in place, more will gradually pop up over time. Clicking no does not stop more spawning.

Looking at the process list, they do seem to be coming from wsl and the command line is a variation on:

msrdc.exe /v:2E0C5CDE-CE45-4D11-849B-8C4B694268A5 /hvsocketserviceid:BA7142FC-FACB-11E6-BD58-64006A7986D3 /silent /wslg /plugin:WSLDVC_PACKAGE /wslgsharedmemorypath:WSL\2E0C5CDE-CE45-4D11-849B-8C4B694268A5\wslg "C:\Program Files\WindowsApps\MicrosoftCorporationII.WindowsSubsystemForLinux_1.0.3.0_x64__8wekyb3d8bbwe\wslg.rdp"

They even seem to popup whilst wsl --list --verbose shows the installed distro as stopped. I have not clicked "yes" on one to see what it does!

Expected Behavior

No random popups!

Actual Behavior

Random popups...

There is a workaround.
Disabling WSLg in %USERPROFILE%.wslconfig removes RemoteApp popups:

[wsl2]
guiApplications=false

I have the same issue and noticed that on my install the wslg.rdp file is missing.

[cwarlich]

Same issue here: I get this message once after WSLg starts and after clicking yes. It only reappears after wsl --shutdown followed by starting wsl again.

@lalku: Although I do not see why RDP should be involved: Where is wslg.rdp supposed to be located and what should it contain? Does adding wslg.rdp fix the issue?

[lalku]

From the initial message it should be located at
C:\Program Files\WindowsApps\MicrosoftCorporationII.WindowsSubsystemForLinux_1.0.3.0_x64__8wekyb3d8bbwe\wslg.rdp

[DevRCRun]

The file is present and currently contains:

audiocapturemode:i:2
authentication level:i:0
disableconnectionsharing:i:1
enablecredsspsupport:i:0
hvsocketenabled:i:1
remoteapplicationmode:i:1
remoteapplicationprogram:s:dummy-entry

I am seeing the same thing, with the exact same wslg.rdp. I believe https://github.com/microsoft/wslg might be a more appropriate repository for this one, for two reasons:

1. Disabling WSLg solves this, compare RemoteApp - "identity of remote computer could not be verified" popups since 1.0.3.0 #9347 (comment)
2. Until I acknowledge the popup, no GUI applications (xeyes, ...) are working, while they are working as soon as I acknowledge the popup.

I filed microsoft/wslg#997

I think it is also related to microsoft/wslg#841

There is a workaround. Disabling WSLg in %USERPROFILE%.wslconfig removes RemoteApp popups:

[wsl2]
guiApplications=false

Doesn't this disable GUI apps entirely though? I don't want to do that, but I do want the damn popups to stop...
