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.

After running the Windows Activation Wizard and performing the required changes to the registries and activation scripts, the application allows you to start enjoying the new version of Windows XP with no worries related to manually activating your product.

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.

The application proves obsolete with Windows Vista and later, since they all offer the possibility of changing the product key by simply typing it in the Windows Activation window.
