Yes if your one of the millions of people who have Microsoft pirated CD's.
These are your alternatives.
1- Disable Windows update - If you don't your windows operating system will be locked. And you will not be able to sign on to your computer again. Losing your valuable data. Because the only real way out is to buy a license version of windows or reformat your hard drive again.
2- Window has been telling us for years that they were going to lock people out of their pc's if they have pirated software. Guess what they're doing it now.
3- If you bought a pc from a vendor and windows is telling you that you have a pirated windows license. Windows will give you a new license. But here's the catch. You have to rat out on the vendor or individual who sold you that computer.
The task from what I hear is tedious but for a free license that's what you have to do.
