How to Reveal the Hidden Devices in your Computer

There is a list of hidden devices that do not normally show up in the Device Manager. You can get XP to reveal these devices by either changing a Registry entry, or by creating a batch file to launch the Device Manager with the correct options.


If you’re comfortable with the Registry, open the Registry Editor and navigate to

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Session Manager\Environment\.


Here, create a String Value called DEVMGR_SHOW_NONPRESENT_DEVICES, and give it a value of 1. If you’d rather create a batch file, open Notepad, and type in the following:

@Echo Off
Prompt $p$g
start devmgmt.msc

Then save it as “devmgmt.bat”. You can use any descriptive filename you like with the .bat extension.
