Smart System Informer is a simple, compact system information tool.
Launch the program and it will display the basic details immediately: your Windows version, computer and user names, BIOS details, CPU, video card and available RAM.
The Drives tab provides links to your connected hard drives, showing you their used and free drive space.
And there are tabs to show you your running processes, startup programs and installed applications.
You get a few useful extra features here. View your Startup programs, for instance, and if you find one you don't recognise then selecting it and clicking "Ask Google" will open a browser window with the results of a web search for that file.
For the most part, though, Smart System Informer really isn't that smart at all (our 64-bit test PC had 16GB of RAM, for instance, but the program only reported 4GB).
It's also annoying that such a basic tool has to be installed; it really should be portable. And so, on balance, you'll probably be better off elsewhere.
