Do check out msinfo32.exe. Virtually everything that you would want to know about the system configuration of a Windows machine will be revealed with this command. Msinfo32.exe is located under /Program Files/Common Files/Microsoft Shared/MSInfo (at least on our system). If you wish to dump the report to a file, use:

msinfo32 /report reportname.txt

It takes a while for the report to run, so be patient. If you run the application with no options, it will bring up a GUI so you can view the information. To view the information of another machine, use:

msinfo32 /computer \computername
