Karen’s Powertools have long been a favourite of mine. Check out her latest: an updated version of her Computer Profiler. The program “displays hundreds of bits of information about your computer and the software it uses. Programs you’ve installed, facts about your disk drives, printers, memory, and network connections, even dozens of details of Windows itself, are all revealed by the Profiler.”
This is a bit geeky, but this kind of data can be useful if you need to find out what’s going wrong, or your PC vendor asks awkward questions when you’re trying to get them to fix something. This version not only covers USB devices but also reports every USB device you’ve ever connected to your computer.
The software’s free, but if you want to support her, buy a CD of all her work.
