Hi all,
Untill last week (early july 21), on about forty of our clients we ran a edge legacy based kiosk mode that we set up with powershell command "Set-AssignedAccess -AppUserModelId Microsoft.MicrosoftEdge_8wekyb3d8bbwe!MicrosoftEdge -UserName "kioskuser"". All was working smoothly for more than a year.
Unfortunately, after patching those clients, CU for Windows removed edge legacy and installed edge chromium instead. The blue screen with kiosk error code 0xffffffff now appeared when starting those kiosk clients.
We cleared assigned access with "Clear-AssignedAccess" and tried to set up kiosk with the powershell command "Set-AssignedAccess -AppUserModelId MSEdge -UserName "kioskuser"" (we changed the AppUserModelId parameter to the AUMID for Edge Chromium (MSEdge), which we found with the command Get-StartApps).
Bad news: it fails with error "New-CimInstance : One or more parameter values passed to the method were invalid....."
Our Windows Version is 20H2 (OS Build 19042.985), Edge Version is Edge Stable Ver. 91.0.864.67
Can anyone tell me wether theres a way to set up kiosk with Edge Chromium with Powershell command Set-AssignedAccess? And without Beta or Insider Preview Software, as we don't want to run this kind of software in production environments.
At the moment the only way to set up kiosk mode successfully is to do this manually via settings -> accounts -> other users -> Set up a kiosk, as we don't yet use InTune or whatever.
Thank you in advance
Norbert
