A couple of weeks ago, Microsoft documented an issue affecting several Windows 10 and 11 customers who were reporting instances of Blue Screen of Death (BSOD) with error messages of “UNSUPPORTED_PROCESSOR”. This problem was seemingly impacting MSI customers who had installed the optional preview Windows update in August 2023, but after conducting an initial investigation, Microsoft emphasized that it was not to blame for these BSODs. Now, MSI has taken ownership for the issue and rolled out BIOS updates for affected motherboards.
