I particularly like this little tool ;)
SIW is a system information tool that gathers extensive information about your system properties, hardware and settings. It includes detailed specs for CPU, Network, TCP/IP, Memory, Hardware, Users, Network Shares and more, as well as real-time monitors for CPU, Memory and network traffic. SIW also displays currently active network connections, installed codecs, connected MS SQL and Oracle database servers (if any) and more. It also lists the product keys for everything installed on you system. Other features include a report generator (HTML, CSV, TXT and XML), a MAC address changer, remote computer info and more. SIW is a standalone software that does not require installation.
