    Hi, I found this searching for “Show Nonpresent Devices” as I can never quite remember it, but I had been entering it into the Environment Variables (Sys Properties, Advanced) window before launching Device Manager. Your way is not only more direct but offers an extra benefit…

    Take the last two lines (i.e. ignore the cmd bit) and paste them into Notepad. Save as ShowNPDevices.bat. Now you don’t need to remember it, just click the .bat file and you’re into DevManager with the flag set.

    It’s worth adding that you still need to go View Show Hidden Devices after setting the flag though.

    Sorry if this is a tad oversimplified for yourself but I figure you’re one of the highest Googles for it so I thought I’d explain it for anyone.

    Thanks,

    - David

    Anothing thing to mentioned when you open the terminal to type

    cmd
    set DEVMGR_SHOW_NONPRESENT_DEVICES=1
    start devmgmt.msc

    Do not close the terminal till your work is done. Once you are finishing removing unneeded devices then you can close the terminal typing “exit” or whichever way you want.

    I found myself trying to figure why it would not work for me because I would tend to close the terminal.

    David.
