Microsoft has started the forced rollout of Windows 11 24H2 to eligible, non-managed systems running the Home and Pro editions of Windows 11 22H2 and 23H2.
The change also affects standalone Office versions, including Office 2024, Office 2021, Office 2019, and Office 2016.
Microsoft will stop supporting Office apps on Windows 10 this year. Also it really wants you to upgrade to Windows 11.
