Microsoft has announced that it will end support for Microsoft 365 apps on Windows 10, marking a significant shift in its software strategy. This move aligns with the company's push toward Windows 11 adoption and modern productivity solutions. Here's everything you need to know about this upcoming change and how it affects your workflow.

Microsoft 365 Retirement Timeline

Microsoft has confirmed that:

This phased approach gives users and businesses time to transition, but planning should begin now to avoid disruptions.

Why Microsoft is Making This Change
