SIW is an advanced System Information for Windows tool that gathers detailed information about your system properties and settings and displays it in an extremely comprehensible manner.

SIW is so powerful it has the ability to recover lost passwords, show you your windows product key, your motherboard's PCI devices (useful for locating drivers), and perform several network commands.

What I really like about the software is that it comes in a standalone *.exe file, which is very convenient to me as a computer repair/troubleshooting guy. I can carry this small 1.7 MB file on a cheap flash drive and perform many tasks.

Here are some screenshots of SIW's other features:
