Removing Drivers for Non-Present Hardware

October 25, 2009

Windows often remembers hardware bindings for devices that are no longer connected to your computer. Sometimes these old bindings cause problems.

To view the bindings for non-present hardware you need to do the following:

  • Start -> Run -> cmd
  • At the cmd prompt type:
    • set DEVMGR_SHOW_NONPRESENT_DEVICES=1
    • devmgmt.msc
  • When the Device Manager console starts select the menu item View -> Show hidden devices

Non-present devices will now show up greyed out in the device manager tree. Remove the troublesome device by selecting it and pressing the “Delete” key or Right-clicking and selecting Uninstall.

Warning! Don’t delete any devices that are required to boot your computer. Plug-and-Play devices are generally safe to remove (ie. USB, PCI, etc…)
