Question

How much does it cost to activate Windows?

Community Answer

It doesn't cost anything. When you buy your Windows, you get an activation key. So, the cost would just be the cost of the OS.

Question

My laptop shows that Windows is not genuine. What should I do?

Community Answer

You need a product activation code which you can find included with your installation CD. If it is a pirated version, you can feel free to ignore the warning, but it will not go away.
