Sometimes simple is best, and that's definitely the case with Product Key Finder. This free and portable product key tool runs straight from the download file, so there's no need to install. Simply clicking on the file will bring up a window containing the names and product keys for the applications it finds installed on your registry.

Apart from just listing them, Product Key Finder can also save the list as a .CSV file from which you can cut, copy and paste the keys as needed. Product Key Finder also works with a few command line options - you can find further details on the program's website.

Product Key Finder is simple in the extreme, but sometimes that's just what you want. Don't be surprised by the program's total lack of options and configuration settings - it simply doesn't have any - but its streamlined approach does make it simple, quick and effective.

Product Key Finder - simple in the extreme, but totally effective.
