There are several paid and free tools that help you view your system’s properties and most of them do a good job of what they are expected to do.
However, there is this free tool called SIW or System Information for Windows (http://www.gtopala.com/) that really stands out for the sheer amount of information that it reveals to you about your system, all displayed in an extremely comprehensible manner . SIW gathers detailed information about your operating system, installed software, drivers, hardware, network – to name a few.
Of course, all of these info would be an overkill for the average computer user, but if you are somewhat of a computer geek then you might find these information both interesting and useful.
SIW is available both as a free version as well as a paid version.
