New! You can get a beta version of the next Unknown Devices with Windows Vista support.

I also setup new forums! Visit http://forums.halfdone.com, where you can post comments and bug reports about the site and Unknown Devices. As always you can still email me directly if you wish otherwise.

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.

Program supports Win95, 98, 98se, Me, 2k, XP and 2003 but not NT. It also attempts to support future OSes.
It runs fine from a CD or floppy. It's free for personal and (especially) business use. The program contains no adware, spyware, malware, popups, or whatever is the latest name for junk software. If you want to add it to a cd collection or magazine that is fine, just drop me an email.
