Think you know the innards of your Windows system? Well think again. Download and run SIW, and you’ll realize just how little you know. It’s probably the most comprehensive free system analyzer you’ll find anywhere. It gives you a complete rundown of all your hardware and software, your system setup, your audio and video codecs, your motherboard, network cards, systems slots–and that’s just the beginning. It also includes real-time monitors for things such as network, RAM, and CPU use.

How much detail does it give? Consider these few bits of data. It will tell you the temperature of your CPU — and if you’ve got a dual-core processor, it will show you the temperature of each. It’ll even tell you the temperature of your hard disk. And it somehow also managed to report on your software license keys as well, including for Windows and your installed software.
