What are other methods to fix my Windows computer?

If you have a Windows 10 computer, the same problem arises there and it’s recommended that you learn how to fix that issue if it ever comes up. You still have to update your drivers manually and check your GPU for hardware issues.

Another error you may encounter is the Windows Subsystem for Linux register error that gets in the way of a Linux installation. Although this solution is mainly for developers and other people who dabble in Linux.

More common are when Windows 11 drivers become unavailable. In this instance, you may have to reinstall the driver again or outright manually do it yourself. Fortunately, it’s easy to do; much easier than fixing the kernel-mode error.
