Universal Windows XP Activator

There is no universal Windows XP activation key. Each program comes with a unique activation key. The exception to this rule is when you purchase a business pack that comes with multiple keys. When you purchase a computer that has Windows XP installed on it, the key will be attached to the machine. If you purchase the cd, the key is in the packaging.
