The kernel bug is one of Windows's critical bugs. If you've ever met the blue screen of death (BSoD), you've seen a kernel bug. Windows is actually a multi-layer program that works together. You might think of Windows as if you were your body, working a lot of pieces to make it whole, and just like your body, certain parts of Windows are more important than others.
The kernel is the most important part of Windows. This includes critical programs to handle things such as memory management and graphics card drivers. These programs are like heart and brain in the body. If something in the kernel crashes, all windows will often crash.
Since there are many programs in the kernel, there are many ways to display errors. Although Microsoft is carrying out extensive testing to overcome errors, testing facilities are unable to trace the combinations that billions of computers use with Windows when some errors go through.
However, many of the kernel bugs are corporate-written device drivers that are hardware rather than Microsoft. For example, a graphics card is likely to use a video monitor driver. These companies often collaborate with Microsoft to test drivers, but the cooperation of companies results in further complexity.
Hardware failure may cause a kernel failure. If the graphics card fails, you may send incorrect data to the graphics device driver that crashes, resulting in a kernel failure. If your hard drive fails, files used by Windows may be damaged and programs that have encountered these files.
Registry Errors may cause kernel errors. A registry is an information database that Windows uses to store program information. If the registry is corrupted, the programs it uses may cause kernel errors.
The registry may be corrupted due to software or hardware failure. Corruption in software may result from a program failure that issues information to the registry. Or, if you turn off your computer without turning off the system completely, registry files may not be fully written to the disk. A hardware failure may occur if the hard drive fails, which is why some of the registry files are lost. It's a good idea to research the kernel bugs and other registry.
