The following review written by one of the Software Informer contributors applies to version 2.0
Ultimate Key Finder is an extremely simple free tool designed to help you keep a backup copy of most of your serial numbers and Product keys. The program will look and retrieve the product IDs of all of your main applications, allowing you to save them as a CSV file for future use.
Despite its simplicity, this utility is of a high value for all computers. Actually, there are various instances in which you will need to re-install all of your system’s applications, including your operating system. For instance, whenever you change or upgrade your hard drive or your computer, or simply when your system crashes. Having to re-install your Windows OS, your copy of Microsoft Office, of your Adobe products, and any other big software applications is tedious enough, not to mention the fact that we sometimes spend even more time trying to find those elusive and long-forgotten serial numbers. Using Ultimate Key Finder, you can save in one single CSV (Comma Separated Values) file all those valuable product IDs that you may need again someday. If you prefer, you can transform this CSV file into an Excel file easily. Whatever the format you use to store it, remember to keep a copy of it outside your hard drive, just in case.
