Solution 2:

Nirsofts ProduKey is small and well-trusted.

Note: some antivirus software may detect this as a virus. None of NirSoft's products are viruses but they can be used by them. Read: http://www.nirsoft.net/false_positive_report.html

Solution 3:

There is Belarc Advisor, free for personal use. It scans your computer for several minutes and finds all the product keys stored on the PC, including the Windows OS product key.

The Belarc Advisor builds a detailed profile of your installed software and hardware, missing Microsoft hotfixes, anti-virus status, CIS (Center for Internet Security) benchmarks, and displays the results in your Web browser. All of your PC profile information is kept private on your PC and is not sent to any web server.

Note: I am not in any way affiliated with this product; have used in the past to extract my OS product key, as well as my Office key.
