Remove unused hidden devices

[Eastcoasthandle]

I came across a thread that discuss how to remove uninstalled hidden devices like your vidoe card (also found in the sub section of sound from your Device Manager) displays, etc. Read this link for more details. This may help those who were having problems with newer cats

Wow, I must have been the only 1 that found a few profiles of ATI in my device manager that needed to be delete

I didn't find anything that needed to be deleted. But that's probably 'cause I just reformatted.

Found damn near everything since my ti4400 in there...thanks.

Examples included but not limited to:
-Install of different CPUs without a complete reinstall of XP
-Install of different video cards
-Install of different sound cards
-Use of USB components that have been switched to a different USB port.
-Use of different CD/DVD roms
-Etc

To show hidden, uninstalled device profiles without having to type those command lines each time, here is what you do:

In the registry go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Session Manager\Environment add a string value, name it DEVMGR_SHOW_NONPRESENT_DEVICES
and set its data equal to 1.

Anyone else have any duplicate device profiles (not drivers)

Alternatively, you can also add the string to the environment variables found here:

System Properties Advanced Tab > Environment Variables > System Variables

Create a new variable with the devmgr_show_nonpresent_devices text and a value of 1.

Good info, thanks!
