Turn off Windows Installer RDS Compatibility

ComputerIntune-readyTS_DISABLE_MSI

Supported on At least Windows Server 2008 R2

25H2 · 1.0

What it does

This policy setting specifies whether Windows Installer RDS Compatibility runs on a per user basis for fully installed applications. Windows Installer allows one instance of the msiexec process to run at a time. By default, Windows Installer RDS Compatibility is turned on. If you enable this policy setting, Windows Installer RDS Compatibility is turned off, and only one instance of the msiexec process can run at a time. If you disable or do not configure this policy setting, Windows Installer RDS Compatibility is turned on, and multiple per user application installation requests are queued and handled by the msiexec process in the order in which they are received.

What it writes

The OMA-URI is an inferred ADMX-backed Policy CSP candidate derived from the source ADMX file name and policy name.
Some Microsoft policies use built-in Policy CSP pages whose area names don't match the ADMX file name, so verify the candidate against Microsoft Learn before deployment.
