microsoft store office

The microsoft store office tag covers Microsoft’s transition away from the Microsoft Store installation type for Microsoft 365 Apps on Windows. Microsoft has already stopped feature updates for affected installations and plans to end security updates in December 2026. The apps will continue to open for now, but users whose Office account information identifies the Microsoft Store version should plan to migrate to the Click-to-Run installation model. This archive focuses on the support timeline, what the change means for Microsoft 365 users, and the practical steps involved in moving to the supported distribution method.
