MSI has released BIOS updates to fix a known issue that triggers blue screens of death on Windows computers after installing August 2023 preview updates.
"The new BIOS coming will include an update on the Intel CPU uCode which will prevent any more messages regarding the 'UNSUPPORTED PROCESSOR' issues. This upcoming update will correspond to both 13th-generation and newer ones," MSI said on Wednesday.
The complete list of BIOS updates released so far that address this known issue can be found in the table below.
MSI's announcement comes one week after Microsoft blamed the blue screen issues that hit its customers after installing last month's preview updates on OEM vendors.
Microsoft first acknowledged the issue two weeks ago, two days after releasing August's optional cumulative update, saying that affected systems include those running Windows 11 21H2/22H2 and Windows 10 22H2. Redmond said at the time that the buggy optional updates "Might automatically uninstall to allow Windows to start up as expected" and warned users not to reinstall it to avoid further problems.
