Registry key location for software deployed via Group Policy?

  • 772

I need to trigger a particular GPO-deployed application to reinstall. In the past I've just deleted a certain registry key that tells Windows: "this application has been installed".

But I can't for the life of me remember where those keys are located in the registry, and searching isn't turning much up.

Thanks!

    Look in:

    HKLM\Software\Microsoft\Windows\Current Version\Group Policy\AppMgmt. Find the key that corresponds to the software you're looking for, and delete it. Then run gpupdate /force and restart.

  2. I believe:

    GPO applied to the local computer: 

    HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Group Policy\History

    GPO applied to the currently logged on user:

    HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion
  \Group Policy\History

  3. Instead of deleting the key, you can also set the AppState value to 0. The original value should 9 or 17 (with removal option).

    Get-ItemProperty `
-Path "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Group Policy\AppMgmt\*" `
| ForEach-Object {
  if ($_. "Deployment Name" -match '^<the deployment name>$') {
    $_

    $answer = Read-Host "Set value?"

    if ( $answer -match "(?i)Y") {
      New-ItemProperty $_.PSPath -Name AppState -Value 0 -Force
    }
  }
}

  4. Not a direct answer, but if you go into the GPO and right click the Application object go to All Tasks -> Redeploy. That will well redeploy the application.
