It must be a day with a 'y' in it -- there's a problematic Windows 11 update causing blue screens
Microsoft has once again been forced to mitigate a problem caused by a faulty update for Windows 11 with a Known Issue Rollback (KIR).
The KB5055523 update, release earlier this month is causing BSoDs and a 0x18B error. The same issue applies to the KB5053656 preview update from March. While it used to be possible to refer to KIRs as a rarely used fix for particularly serious issues, it is something Microsoft is falling back on more and more. The problem is, they don’t work for everyone.
