MSI brings a fix for Windows 11’s ‘UNSUPPORTED PROCESSOR’ error

Last month, Windows 11 update KB5029351 led to the occurrence of the “UNSUPPORTED_PROCESSOR” error on certain devices. This error message was displayed on a blue screen of death (BSOD) and indicated that the device’s processor was incompatible with the update.

The “UNSUPPORTED PROCESSOR” blue screen of death (BSOD) error occurs when the computer’s processor is not supported by the BIOS. This happens if users have a newer processor than what is supported by the motherboard, or if users have a processor that has been overclocked.

Reportedly, MSI has released a fix for the “UNSUPPORTED_PROCESSOR” error that some users were experiencing after installing the KB5029351 preview update for Windows 11.
