Microsoft Has a Fix for Windows’ Latest Blue Screen Problem

If your Windows computer is crashing unexpectedly and showing you a blue screen error, there's now a fix for that.

As BleepingComputer reports, Windows updates pushed in March and April are triggering a secure kernel fatal error, causing devices running Windows 11 version 24H2 to crash and display a blue screen exception with error code 0x18B, indicating a SECURE_KERNEL_ERROR.

To address this issue, Microsoft has released a Known Issue Rollback (KIR), which is a quick, targeted fix for non-security bugs. It's a temporary solution since it rolls back earlier updates, while the company works on a new update to patch the problem. Here's how to apply it to your device.

What Windows users need to do

If you have a personal or non-managed work computer running Windows 11, the resolution will automatically be pushed to your device from Windows Update and Microsoft Update in the next day or so. According to Microsoft's support page, restarting may help the fix apply faster. As such, make sure you reboot your PC in order for this latest update to take effect as soon as possible.

For enterprise devices managed by IT departments, the issue will resolve once your network admin installs and configures the Windows 11 24H2 and Windows Server 2025 KB5053656 250412_03103 Known Issue Rollback Group Policy. The Group Policy can be found under Computer Configuration > Administrative Templates > . You will also need to restart any affected devices to apply the group policy settings.

The blue screen bug follows Microsoft's big Patch Tuesday update, which fixed 134 security vulnerabilities in Windows—including one actively-exploited zero-day flaw. It also comes as Microsoft is testing out a new blue screen design altogether. Soon enough, future crashes like this will look different, though the company's procedural response will likely remained unchanged.
