Cool Hardware Diagnostic Tool!

By: Arie Slob

The hardware diagnostics tool (Hwdiag.exe) which was first included in Windows 95 OSR2, is included in Windows 98. To start, type hwinfo /ui in the Run box on the Start menu.

Hwdiag.exe lists every key in the Windows Registry that refers to hardware in your system. The entries are color-coded:

  • Registry entries are displayed in green
  • File attributes in magenta
  • Configuration Manger information in brown
  • Error messages in red
  • Warnings are displayed in blue
