To date, Windows has been used most commonly on the x86 processor. The x86 implements a protection mechanism that lets multiple programs run simultaneously without stepping on each other's toes. This protection comes in four levels of privilege or access to system memory and hardware. Two of these levels are commonly referred to as kernel mode and user mode.

Kernel mode is the most privileged state of the x86. Both the Windows OS and drivers are considered trusted, and, therefore, run in kernel mode. This ensures unfettered access to system resources and the ability to maximize performance. Other software is assigned to user mode, the least-privileged state of the x86, restricting direct access to much of the system. Applications, such as Microsoft Word, run in user mode to guard against applications corrupting system-level software and each other.

Although kernel-mode software is protected from applications running in user mode, it is not protected from other kernel-mode software. For example, if a driver erroneously accesses a portion of memory that is being used by other software (or not specifically marked as accessible to drivers), Windows stops the entire system. This is called a bug check or a crash, and Windows displays the popularly known Blue Screen of Death (BSOD). About 95% of Windows system crashes are caused by buggy software (or buggy device drivers), almost all of which come from third-party vendors. The remaining 5% is due to malfunctioning hardware devices, which often prompt crashes by corrupting memory contents.

Another little-known fact is that most crashes are repeat crashes. Few computer technician can resolve system crashes immediately. As a result, they typically happen again and again. It's common to see weeks and months pass before the answer is found. By solving a crash immediately after the first occurrence, you can prevent time-consuming and costly repeat crashes.

An advanced repair tool for windows finds and repairs system errors and incorrect information in the windows system registry. An optimizer removes obsolete and duplicate entries that Windows and other programs leave behind. These invalid entries which gets inside to your system registry are the ones making your windows system crash frequently.

With the aid of a unique and one of a kind technology which repairs over 60,000 windows errors and is guaranteed to fix problems on your system, you will no longer call for a professional computer technician and pays a lot of money. You can do it yourself within just a minutes only by clicking your mouse.
