Dont you hate when you have to reformat your hard drive or when it breaks? Well you probably think to yourself "I'll just reinstall" and realize !@#$ i lost the sticker with my cd key, or the kids tore it off, or the sticker on the top of your desktop rubbed off from over use and overflow of cds. fear not I HAVE YOUR SOLUTION.
Step 1: Tools
You will need your Windows XP CD, your computer (now if you are thinking, my computer wont work without finding out the cd key, your wrong you can install the 30 day trial) and to calm down lol.
Step 2: First step
Insert the XP disk in your pc or someone else's i don't care. Right click and press explore.
Step 3: Step Two
Click on the folder that says i386, and find the file named UNATTEND.txt, copy it to your desktop (click and drag). open the file and press ctrl+f and type "ProductKey" and there it will be in ""
Step 4: Microsoft problems
if you are changing hard drives you may want to call microsoft to get a new key but if the one you found on your disk works then dont bother, Hope you enjoyed my first instructable.
