Microsoft announced the general availability (GA) of new Power Apps application for Windows. This builds on the public preview announced April 2022 in Announcing Public Preview of a new Power Apps application on Windows.

If you installed the app during the Public Preview, you don’t have to do anything – the app will automatically update and be renamed “Power Apps”. For everyone else, you just have to install the brand new “Power Apps” application from the Microsoft Store.
