Software providing system configuration?


Beta member
hi all, i would like to enquire from u guys is there any programs that could display system configurations in a glance. I understand that there is a program called "WCPUID" which displays the system configurations in one glance but it shows mainly on the hardware side of the pc. Is there other programs which are able to show stuff such as the windows service pack of the system etc rather den having to go into add/remove programs to look for the programs installed?
