This Halfdone Unknown Devices freeware gets our vote as a pretty useful utility to have in the toolchest. Fire it up and it will scan your computer for devices and let you know what they are, so you can take appropriate action. If you’ve ever been on the receiving end of one of those naff yellow question marks in Device Manager you’ll be grateful for this puppy.
Hey, it’ll even give you the Product Key used for your version of Windows (jot it down in case you need to do a re-install one day). Bonus!
Unknown Devices helps you find what those unknown devices in Device Manager really are. By checking Device Manager for unknown devices and extracting information from it, this program attempts to figure out what the device is. You might not have to open your case or look up random numbers off of PCI cards to figure out what they are.
