Unexpected crashes on Windows computers, particularly those running Windows 11 version 24H2, have been a source of frustration for many users. Reports indicate that recent updates released in March and April have led to a secure kernel fatal error, prompting devices to display a blue screen exception with the error code 0x18B, signifying a SECUREKERNELERROR.
In response to this issue, Microsoft has introduced a Known Issue Rollback (KIR), which serves as a swift and targeted remedy for non-security-related bugs. This temporary fix involves rolling back specific updates while the company develops a more permanent solution. Users can easily apply this rollback to their devices.
What Windows users need to do
For individuals using personal or non-managed work computers, the resolution will be automatically deployed via Windows Update and Microsoft Update within the next day. To expedite the application of this fix, Microsoft recommends restarting your PC. A simple reboot may help ensure that the latest update takes effect promptly.
For enterprise devices under the management of IT departments, the resolution will occur once network administrators install and configure the Windows 11 24H2 and Windows Server 2025 KB5053656 Known Issue Rollback Group Policy. This policy can be located under Computer Configuration > Administrative Templates. A restart of any affected devices will also be necessary to implement the new group policy settings.
This blue screen bug surfaced following Microsoft’s significant Patch Tuesday update, which addressed 134 security vulnerabilities in Windows, including a zero-day flaw that was actively being exploited. Interestingly, this issue arises as Microsoft is experimenting with a revamped blue screen design, suggesting that future crashes may present a different visual experience, even as the company’s procedural responses remain steadfast.
