Belarc Advisor is one of the handiest programs going, especially for IT types. The program creates an HTML report that not only tells you everything you could possibly want to know about the hardware on your system (except perhaps why it doesn't work correctly!), but also what you might need to know about the software that's installed. Gathered info includes motherboard type and revision, CPU and GPU info, drive space, Microsoft hotfixes, operating system revision, and Web browser vulnerabilities, as well as third-party software installs.
