Find and Identify Unknown Devices

Posted on January 5, 2010. Filed under: Computer, Freebies, Softwares, Super Fast Updates, Windows/7 | Tags: , , , , , , , , |

   Here is a tiny tool called Unknown Devices (UKD) which is used to identify unknown devices that are not recognized by Windows in your system especially after you reinstall your system and cannot figure out what all those yellow question mark labeled devices really are.

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.


  • Press F3 to search the selected text on the internet. (Ctrl-F3 to search without the "+drivers")
  • Press F2 or Ctrl-C to copy selected to clipboard
  • Using an item under Full Details for a web search will likely give you better results


  • This program only knows about PCI and AGP devices. It will not be able to help with ISA based devices and original PCMCIA cards.
  • Also this program shows all devices found in the registry including devices that no longer exists!
  • This program might not display the unknown icon for some devices even if Windows really doesn’t know what it is.
