Microsoft Intune or Endpoint Manager is awesome but also a pain if something does not work as expected. For example, if you create a package that simply imports a reg file, it will import the keys under SOFTWARE\WOW6432Node (WOW or SysWoW means Windows32OnWindows64). This is normal behaviour because Microsoft Intune Extension runs as a 32 Bit process on Windows. Therefore it does not know about the 64 Bit architecture.

So the solution is to run the reg command with this option. This will import the keys directly under SOFTWARE\…

reg import file.reg /reg:64

There are other approaches to this but my solution works and is the fastest in my opinion.

If you are having issues with Microsoft Teams Meeting Addin missing in Outlook, here are a few tips:

1. Make sure Microsoft Teams Meeting Addin is installed and present in the Control Panel
2. Navigate as admin to C:\Program Files\WindowsApps\MSTeams_23320.3021.2567.4799_x64__8wekyb3d8bbwe (Version number might have changed)
3. Copy MicrosoftTeamsMeetingAddinInstaller.msi
4. Run the following command:
   • msiexec.exe /i “MicrosoftTeamsMeetingAddinInstaller.msi” ALLUSERS=1 /qn /norestart TARGETDIR=”C:\Program Files (x86)\Microsoft\TeamsMeetingAddin\1.23.33413\” (Version number might have changed)
5. Also, make sure this key is set on the user side. You could make a GPO or Intune script for that
   • HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\Outlook\Addins\TeamsAddin.FastConnect
   • “Description”=”Microsoft Teams Meeting Add-in for Microsoft Office”
   • “FriendlyName”=”Microsoft Teams Meeting Add-in for Microsoft Office”
   • “LoadBehavior”=dword:00000003

Download button inside WIndows Updates greyed out? This could be because of a GPO which sets the following registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate

SetDisableUXWUAccess 0 (1 greyed out)

If you want to apply the settings without restarting your server/computer, restart Windows Updates service.

Here is a tip if you are having issues with Microsoft 365 Apps when trying to login to activate Office (error 1200).

• Update to the latest Microsoft Apps version
• Delete content in these folders:
  • C:\Users\user\AppData\Local\Microsoft\IdentityCache
  • C:\Users\user\AppData\Local\Microsoft\OneAuth
  • C:\Users\user\AppData\Local\Packages\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy
• Run powershell as user (non admin)
  • Add-AppxPackage -Register “$env:windir\SystemApps\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy\Appxmanifest.xml” -DisableDevelopmentMode -ForceApplicationShutdown
  • Add-AppxPackage -Register “$env:windir\SystemApps\Microsoft.Windows.CloudExperienceHost_cw5n1h2txyewy\Appxmanifest.xml” -DisableDevelopmentMode -ForceApplicationShutdown
• Delete Subkeys under
  • HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Identity\Identities
• Reboot and try logging in to Microsoft Apps

Roughly a year ago I had an issue with grey screen on Windows Server 2022 with Citrix Virtual Apps and Desktops. A script helped clear out some registry key but there seem to still be problems with sessions with grey screens. Check out my post from last year: https://www.ajni.it/2023/03/citrix-virtual-apps-and-desktops-2203-grey-screen-connectionfailure-in-eventviewer/

There is a new fix that seems to be better and does not clear any registry keys. Instead it activates Citrix Universal DLL Injection. After upgrading the VDA, make sure this value is set:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\CtxUvi]
“UviEnabled”=dword:00000001

This helped in my environment.
