Microsoft says a Windows 11 update is not to blame for a Blue Screen of Death error that’s been impacting users since last week.
The problem affects PC owners running 600/700 series MSI motherboards for Intel chips. According to users, installing Microsoft’s Windows 11 “KB5029351” update causes their PCs to crash with a Blue Screen of Death error message that says “UNSUPPORTED_PROCESSOR.”
Microsoft has been investigating the problem and concludes that KB5029351 isn’t the main culprit for the crashing problems. “After investigating these reports, we have found that the ‘UNSUPPORTED_PROCESSOR’ error was not caused by issues in KB5029351 and is limited to a specific subset of processors,” the company said in a support document.
The statement is a bit odd since users began reporting the BSOD errors after Microsoft began offering the KB5029351 update as a preview release. In addition, Microsoft is pulling the KB5029351 package from circulation.
“We are collaborating with device manufacturers (OEMs) and will temporarily mitigate this issue by not offering KB5029351 to Windows devices that might be affected by this issue. If you still experience this issue, please contact your device’s processor manufacturer,” Microsoft says.
So far, Microsoft has declined to elaborate. But reading between the lines, it’s possible a recent BIOS version that MSI released for the company’s motherboards last month is causing conflicts with the KB5029351 update.
On Friday, MSI released a statement that noted users can address the Blue Screen of Death errors by installing an older BIOS version for their motherboards. Some affected users also say they were running the newest motherboard BIOS for their the Core i7 13700K and Core i9-13900K
