Starting with the April 2017 Cumulative Update release, devices with an AMD Carrizo DDR4 processor running Windows 7 or Windows 8.1 might start to receive a message that the processor is not supported with those versions of Windows. Microsoft intends to continue to support Windows 7 and Windows 8.1 with this processor and plans to address the issue causing the message in a future update.
The message is triggered once the April 2017 Cumulative Update is installed, and will appear each time a new update scan happens through Windows Update or Windows Server Update Services (WSUS). We do plan to address this issue in a future update.
