The operating system aka OS is what you use when you turn on your computer. Windows XP, Windows 7, 8, and 10 are all operating systems. It is what your computer uses to operate. Without it, you would not be able to use your computer. Sometimes the OS crashes, just stops working for some apparent reason that is beyond us, you get a virus, or you simply want to downgrade or upgrade. Whatever the reason is, I will take care of you.
