Microsoft Certified Professional Magazine Online | Column: Finding the Keys to Your Computers: "Ever wish you could reverse engineer Windows Product Activation enough to figure out what product keys were in use for a given computer? Windows, Office and SQL Server all utilize CD keys (Microsoft calls ‘em Product IDs or Volume License Keys); being able to display these serial numbers can certainly make a software licensing audit easier.

Now, there’s a tool to help: ProduKey from NirSoft does the job. It’s a graphical utility (which can also be run from the command line). The ultimate use: run produkey.exe /remoteall -- it enumerates all computers on the network and loads their product keys. It’ll take forever, but you’ll get a really useful output that can be used to match purchased licenses with installed software. Additional command-line options allow you to target a list of computers in a file, a single computer, and so forth, and output can be directed to a text, tab-delimited, HTML or XML file for convenience."
