After installing the March 2025 Windows non-security preview update (the Originating KBs listed above), released March 27,2025 or later updates, you might experience issues with the update process. After installing the update and restarting your device, you might encounter a blue screen exception with error code 0x18B indicating a SECURE_KERNEL_ERROR.
Resolution: 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.
For enterprise-managed devices managed by IT departments that have installed the affected update and encountered this issue, IT administrators can resolve it by installing and configuring the Group policy listed below. The special Group Policy can be found in Computer Configuration > Administrative Templates > <Group Policy name listed below>.
Important: You will need to install and configure the Group Policy for your version of Windows to resolve this issue. You will also need to restart your device(s) to apply the group policy setting.
Next Steps: We are working on a final resolution that will be part of a future Windows update.
