Windows XP Product Key Modifier 1.0.0a ↓

Automates the task of changing your Windows XP product key.Windows XP Product Key Modifier is an application developed to automatically activate a new product key for Windows XP. It helps you use your new key right away, without the headache of activating it over the phone or reinstalling your operating system. It has a simple user interface, designed even for the most inexperienced of us, where all you have to do is input the new, genuine XP product key. Then sit back for a couple of minutes while it makes copies of the operating system activation script files and automatically runs the Windows Activation Wizard in order to activate your new product key.

While using the application you have to keep in mind that it was designed to perform all the required steps automatically so DO NOT interfere with the Activation Wizard and let the software finish its job even if the wizard window prompts asking you to choose the activation method.
Since the application tampers with the registries and the activation scripts we strongly recommend backing up your data and creating a system restore point before using the application. So just in case it does not work for your version of XP, at least you make sure it does not crash your system.

This Software is ONLY MEANT FOR WINDOWS XP...
