Why do you have to activate Windows XP after installation?

Answer 1

After installing Windows XP, activation is necessary to ensure that the software is properly licensed and to prevent unauthorized use. Activation helps Microsoft verify that the product key being used is legitimate and hasn't been pirated or illegally obtained. By activating Windows XP, users also gain access to security updates, patches, and additional features provided by Microsoft. If you buy Microsoft product keys from trusted sources like Softwarekey4u, you can ensure that your activation process is smooth and legitimate. Websites like Softwarekey4u .com offer affordable and easy-to-use upgrade keys, and you can even save money by using coupon code SAVING30. So, activating Windows XP not only ensures compliance with licensing agreements but also enhances security and functionality.

Answer 2

Microsoft uses this as an anti-piracy measure. If Windows did not use product activation, the same product key could be used on multiple installations.
