Version 2.2.0 provides a module installer that will upgrade any previous version of the module. It is installed per-user by default, but can install per-machine if elevated and installed to a machine-wide accessible location.
Many new cmdlets have been added to get records and summary information, evaluate product packages using ICEs, and to install, repair, and uninstall products and patches.
As with the previous release, backward compatibility is maintained with the initial offering of these cmdlets.
If you have PowerShell 2.0 installed you must first import the module:
With PowerShell 3.0 or newer, invoking any of the installed cmdlets will automatically import the module.
