Show Hidden Devices

You can show hidden devices in the Device Manager. One way is by making a simple registry change. The other is through a batch file.

Registry Change:

1. Go to HKEY_LOCAL_MACHINE \ SYSTEM \ ControlSet001 \ Control \ Session Manager \ Environment

2. Create a string DEVMGR_SHOW_NONPRESENT_DEVICES

3. Give it a value of 1

Batch File

@Echo Off
Prompt $p$g
set DEVMGR_SHOW_NONPRESENT_DEVICES=1
start devmgmt.msc
exit
