Another time you would need the serials is if you had to reinstall Windows e.g. if the hard drive fails or your computer had serious virus infections.
To find serial numbers for installed games your computer must be working and the games installed – i.e. you need to find these keys before you have problems like those mentioned above, not after – if your hard drive has died it is too late.
Game Key Revealer is free and can retrieve the key or serials of over 1,000 games including most of the popular ones:
Download Game Key Revealer from here and save it to your computer – the download link is under ‘Download New Version’ near the top left hand side of the page (not the Download button at the bottom!)
The download is a zip (compressed) file – extract it (usually double click it or just right click on it and choose ‘Extract’) and it will uncompress to a folder called GameKeyRevealer. In that folder look for and run the GameKeyRevealer.exe program file to open the program.
Now click the ‘Find Games’ button and a list of all CD keys and serial numbers from your installed games should be revealed.
Click the ‘Save’ button to save the list to a text file called GameKeyRevealer.txt – it will be saved in the same folder as the program itself. You can now open and print the text file list if required or save it somewhere safe – preferably not on the same computer or you will not have a backup!
