MSI is telling users to refrain from installing a Windows 11 update because it’s causing customer PCs to crash and display the “Blue Screen of Death” error.
For those who already installed it, the company today issued a workaround that can temporarily fix the issue, which began after Microsoft rolled out the OS update on Aug. 22.
The KB5029351 update is designed to offer performance improvements, but for PCs running select MSI motherboards, it appears to trigger a Blue Screen of Death with an “UNSUPPORTED_PROCESSOR” error message.

If you were among the unlucky users who’ve experienced the error, MSI notes in some cases that the KB5029351 update can be automatically uninstalled, allowing the PC to revert back to normal. Hence, these users should avoid reinstalling the update.
“However, if KB5029351 is not automatically uninstalled, we recommend reverting your [motherboard’s] BIOS to the previous version and uninstalling KB5029351 from Windows,” MSI says.
The company created a video on how you can reflash an MSI motherboard with a different BIOS. It essentially involves saving an older BIOS onto a USB flash drive, restarting the PC, and then entering into the BIOS settings during startup. It’s not the most user-friendly solution, but according to MSI it can help restore an affected PC. Users can download other BIOS versions for their motherboard through MSI’s support website.
