DMIDecode alternatives for Windows

Since writing the Dell Service Tag post I have been looking for other methods to get a dmidecode type information from Windows without sacrificing goats to the altar of Microsoft :) One alternative I've come up with is SIW. It's nice and simple, doesn't require installation and also shows more than what you would get using dmidecode in Linux. It also does a listing of PCI devices and lots of other nice stuff such setting the Mac address on network cards. It will also show the Dell Service Tag under Hardware/System Info. It shows up a Serial Number. Update: The author of the software has pointed out to me that it doesn't actually decode DMI. It does do what I have used dmidecode for, so it's still good for the job as far as I'm concerned.
