This small program is one of the best sources for information about your computer that I have found to date. It will display just about anything you want to know about you system, from what hardware and software is installed to networking and serial numbers of installed programs. It is a standalone utility that does not require installation just run the .EXE file, one less installed program on your PC as well the fact that you can run the program directly from a USB flash drive. It runs on Microsoft Windows 98/Me/NT4/2000/XP/Server 2003/Media Center/Tablet PC/Windows 2003 Server R2/Windows Server 2003 x64/Windows XP x64/Windows Vista/. Iím starting to like it more than Belarc Advisor I reviewed a few weeks ago.
