Although it's simple, I find it to be very impressive with the variety of serial numbers and product keys it finds.

Please let us know if a newer version needs a review. LicenseCrawler Pros & Cons What We Like No installation necessary (it's portable). Very easy interface. Can easily copy the keys it finds. Able to export all the keys to a text file. What We Don't Like Results are cluttered with registry details and other non-product key information. Doesn't officially support Windows 11. More Info About LicenseCrawler Here are some more details on LicenseCrawler, including what major operating system and software programs it finds product keys and serial numbers for: Finds Keys for Operating Systems: Windows 10, Windows 8, Windows 7, Windows Vista, Windows XP, Windows Server 2003, and Windows 2000 Finds Keys for Other Software: Microsoft Office version 2013, 2010, 2007, and 2003; most Adobe products; and many more. My Thoughts on LicenseCrawler I was very impressed with LicenseCrawler. At first look, it appeared really simple, and so I didn't expect much. But first impressions are sometimes wrong. Not only did LicenseCrawler find a Windows 10 & 8 product key easily, it also found the serial numbers for several programs that no other key finder program I've used had ever found. Aside from how effective it is at finding serial numbers and product keys, I really liked the simple results window. It's a little crowded with some generally useless registry information, but it's easy to scroll through the results to find what you're looking for. Several programs were found that didn't make a lot of sense — like Internet Explorer and Windows Media Player (neither program requires a serial number, since they're both free and included in Windows) — but that's also a testament to the unique scanning ability of LicenseCrawler. It should be able to locate a seriously impressive list of programs. If you've had problems locating a program's serial number or product key with another key finder program, then I highly recommend trying LicenseCrawler. Download LicenseCrawler The full version of LicenseCrawler is $11 USD and supports blocklist and safelist filters, and will disable the commercial pop-up list.
