Download Article
If you've installed Windows XP and have tried to activate it over the internet, you have probably run into some problems. Because Microsoft no longer supports Windows XP, you cannot activate it online using the traditional activation tool. Fortunately, you can still activate your product key over the phone, or even online by first applying all updates through a tool called Legacy Update. If your product key doesn't work at all, you can deactivate activation entirely in the registry.
Activating Windows XP Easily
Start the activation wizard by clicking the Activation icon in the System Tray, or by clicking Start → All Programs → Accessories → System Tools → Activate Windows. Choose the option to activate by phone and call the toll-free number to request your activation code.

- Visit the manufacturer's support site on another computer. If you are using a laptop or pre-built desktop, you should be able to find all of the drivers you need in one spot. If you're using a custom-built computer, you'll need to find the manufacturer of the hardware that's not working.
- Download the INF files for the hardware piece. Since you can't use an installer, you'll need the actual driver files. These come in INF format. Transfer these files from the working computer to the non-working one via USB or disk.
-
Install the driver. Right-click on the non-working piece of hardware in the Device Manager and select "Update Driver". Browse your computer for the INF file that you downloaded and load it up. You'll be prompted to reboot your computer.
