Remove Old Hidden Devices from a VM after P2V Conversion

One of the most useful terms I constantly search for and I have still not memorized is how to access the Device Manager with the Option to see all hardware (including hidden).

After you have converted a Windows physical server to a virtual machine, some redundant hardware devices may not be removed in the process. This will allow you to go in there manually and see all the hardware that is no longer in use/needed grayed out for you to uninstall manually.
Open a command prompt on the Windows VM and copy/paste (or type…) the following commands
set devmgr_show_nonpresent_devices=1
Once the device management console opens, click on View > Show Hidden Devices.
Tah dah!
Go ahead and uninstall any devices that are no longer required (grayed out).
