Plan for Change: Ending support for Windows 8.1

As mentioned in MC403922, Windows 8.1 reaches end of extended support in January 2023, the majority of Intune customers have already updated their Windows devices so, we will be ending support for devices running Windows 8.1 on October 21, 2022. Additionally, the sideloading key scenario for line-of-business apps will stop being supported since it is only applicable to Windows 8.1 devices. 

Microsoft strongly recommends that you move to a supported version of Windows 10 or Windows 11, to avoid a scenario where you need service or support that is no longer available.

How this will affect your organization:

If you are managing Windows 8.1 devices those devices should be upgraded to a supported version of Windows 10 or Windows 11. There is no impact to existing devices and polices, however, you will not be able to enroll new devices if they are running Windows 8.1.

What you need to do to prepare:

Upgrade your Windows 8.1 devices, if applicable. To determine which users’ devices are running Windows 8.1 navigate to Microsoft Endpoint Manager admin center > Devices > Windows > Windows devices, Filter by OS.
