Microsoft 365 will completely stop supporting Windows 7/8.1/2008 R2 from January 10, 2023
Under normal circumstances, Microsoft provides regular updates to Microsoft 365, in fact, as long as the updates are maintained, it will always be supported, but there are some exceptions. That is Windows 7, Windows 8.1, and Windows Server 2008 R2, these outdated systems will no longer receive Microsoft 365 support from Microsoft.
Microsoft writes: “Even though Windows 7 is no longer supported, we’ve decided to continue to provide you with security updates for Microsoft 365 Apps for the next three years, until January 2023. We’re doing this to give you more time to make the transition from using Microsoft 365 Apps on devices running Windows 7 to devices running a supported operating system, such as Windows 11 or Windows 10. But, during that time, as long as the device is still running Windows 7, your installation of Microsoft 365 Apps won’t receive any new features updates.”
