LicenseCrawler is another well put together free key finder tool.
LicenseCrawler differs from other key finder programs in its almost full-text interface, which I like. I found LicenseCrawler to be very effective at finding serial numbers for the many programs on my PC.
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 2013, Office 2010, Office 2007, Office 2003, most Adobe products, and many more.
