Microsoft is navigating yet another challenge stemming from a problematic update for Windows 11, prompting the company to implement a Known Issue Rollback (KIR) to address the situation.
Update Troubles
The recent KB5055523 update, released earlier this month, has been linked to instances of Blue Screen of Death (BSoD) errors, specifically the 0x18B error code. This issue is not isolated; it also affects the KB5053656 preview update from March. While KIRs were once considered a rare remedy for significant problems, Microsoft is increasingly relying on this solution, although it does not guarantee resolution for all users.
Unlike the KB5053656 preview update, which was only installed by those actively seeking it, the KB5055523 update was automatically downloaded and installed on the majority of Windows 11 devices due to its nature as a cumulative update that includes essential security fixes.
In its official communication regarding the update, Microsoft cautions users about the potential for a blue screen exception, stating: “After installing this update and restarting your device, you might encounter a blue screen exception with error code 0x18B indicating a SECUREKERNELERROR.”
This issue is mitigated using Known Issue Rollback (KIR). Please note that it might take up to 24 hours for the resolution to propagate automatically to consumer devices and non-managed business devices and business devices that are not managed by IT departments. Restarting your Windows device might help the resolution apply to your device faster.
However, this method may not suffice for everyone. For enterprise-managed devices overseen by IT departments that have installed the problematic update, a more hands-on approach is required. IT administrators will need to resolve the issue by installing and configuring the necessary Group Policy, which can be accessed through the provided link.
