See Hidden Devices In Windows on Converted VM’s

Whenever performing a P2V (Physical to Virtual) process, you’ll usually have some devices that are left over in the system which are no longer present. It is best practice to remove these devices from the VM so that it is no loading unnecessary drivers for hardware that’s been removed.

To see hidden devices through Device Manager that are no longer present in the system, follow these steps:

Open up a command window and type in:
SET DEVMGR_SHOW_NONPRESENT_DEVICES=1

Then start device manager from the same command window by typing in:
devmgmt.msc

Choose the option “Show Hidden Devices” under the “View” menu.

Go through the different hardware sections and look for greyed out devices (which represents that they are no longer present in the system) and right click on the device and choose “Uninstall”. This will remove the greyed out device permanently.

Happy converting!
