Let's Get Started - Continued Again
Now refer back to the Serial Key Changer program and simply choose one and type it into the New key field area as shown in the picture above. Once you've done that click the Update button. It will then proceed to update your serial key and bring you back to the Activate Windows by Phone screen. From here you can close this screen; your Windows serial key has been changed.
To confirm that your serial key has changed correctly to the one you choose from the Serial Key Changer Program you need to go ahead and open the Serial Key Viewer program by opening the file "WindowsXP Product Key Viewer.exe" which looks a little something like this.
Step 4 - Now that we have changed your serial key we are ready to go ahead and begin the install process of Windows XP Service Pack 1. Locate the update file and open it, you will be promoted with the "Welcome to the Windows XP Service Pack 1 Setup Wizard", click Next to continue. Next up you will need to agree to the license agreement which is followed by the option to either Archive Files or Do Not Archive Files. It is recommended that you do choose the Archive Files option in case you happen to run into problems after installation.
Now you should have the installation process happening, depending on the speed of your system the update should install in rough 10 - 20 minutes (maybe longer), especially if you choose the Archive Files option which makes the process quite a bit longer.
After the installation process is finally finished you will be promoted to reboot your PC - go ahead and restart your system. Once you are back into Windows you will have Service Pack 1 installed. To confirm that it did actually install okay, go to your desktop, highlight My Computer and press ALT + Enter together and you should see a screen similar to the one below like on my system.
