Windows 11 Update Causing BSODs on PCs with Unsupported Processors
Originally Published 2 years ago — by The Verge

Microsoft is investigating reports of a Blue Screen of Death (BSOD) error message with the code "UNSUPPORTED_PROCESSOR" that is appearing on some Windows 11 PCs after installing a recent update. The issue seems to be affecting systems running Intel processors on MSI motherboards with the latest BIOS updates. Microsoft has pulled the problematic update from affected systems and is working to determine the cause of the problem. It is speculated that the issue may be related to MSI's recent BIOS updates in preparation for Intel's upcoming 14th Gen desktop CPUs.
