If you're looking for an exquisitely detailed audit of your hardware, this is the download you need--no other hardware utility comes close. It starts with the basics, such as the computer manufacturer, installed RAM, hard-disk size, and processor type and speed. But it also shows you the motherboard maker, hard-disk manufacturer, chassis serial number, PC service tag, bus type and speed, multimedia devices...the list goes on and on. You'll also find details about your Windows installation, including which security hotfixes you've installed and which you're missing, plus a list of all user accounts on your PC and a lot more.
