Microsoft is gradually discontinuing its Microsoft 365 applications installed via the Windows Store, instead steering users towards the Click-to-Run installation method. According to official documents, beginning in October 2025, the Windows Store version of Microsoft 365 will no longer receive updates for new features, though security updates will continue until December 2026. To continue receiving updates, users will need to transition to the Click-to-Run version. Both installation methods offer comparable user experiences but differ in architecture and deployment strategies. The Click-to-Run version boasts support for multiple update channels and centralized management. Users can verify their current installation type by checking their account information and effortlessly upgrade if necessary.
