Fix the UNSUPPORTED_PROCESSOR error in Windows with a BIOS update from MSI
It is now a couple of weeks since a Windows 11 update resulted in a large number of people suddenly seeing UNSUPPORTED_PROCESSOR error messages.
At the time, the finger of blame was pointed at Microsoft, although the company was quick to suggest that the fault may be elsewhere. With the issue affecting MSI motherboards, the hardware manufacturer offered up a workaround. Now MSI has released a BIOS update that properly fixes the problem for Intel 700 and 600 series boards.

Microsoft has said that it is investigating the issue, but its announcement was worded quite defensively. The company said: "We are presently investigating to determine if this is an issue caused by Microsoft". Thankfully, MSI has stepped up to the plate and offered up a workaround.

Installing updates for Windows is always something of a gamble, and this is greatly magnified for anyone who chooses to install the preview versions Microsoft releases each month. A good case in point is the KB5029351 update preview that was released for Windows 11 this week.
There are lots of positive changes introduced by this update, but there are also numerous reports of blue screens and UNSUPPORTED_PROCESSOR errors. There's good news and bad news to come.
