I have a sound problem with my window, amazing how this OS can't recognize my onboard sound hardware... when i was fixing this problem, I accidently add a new PnP Software Device Enumerator. Bringin conflict with "Microsoft Kernel DSL Synthesizer", "Microsoft Kernel DRM Audio Desclamer" and others. The error code in all is "Windows cannot load the device driver for this hardware because there is a duplicate device already running in the system. (Code 42)". I can't System Restore and i'm tired of googling solution to my sound problem.

Linux detected that my sound driver is: SoundMax Integrated Digital Audio; 82801EB/ER (is all that i know about it). But when i download that driver, Windows automatically restart after finishing installing the driver. Somehow i found a driver, having sound on all programs but windows still doesn't have(afecting my internet browser, many media player, some video players and all my msger programs). I try to find the way to make windows have sound but i screw it by duplicating the PnP and now i don't want to Format and re-install XP.

Any suggest ideas to: How to remove the duplicated PnP?

PD: sorry for my english

How did you add a new PnP Software Device Enumerator? Knowing that may help come up with a way to remove it.

I search on the web a way to put PnP. It was taking the machine.inf from windows\inf folder, move it to a temporal folder (e.g C:/temp ). Then open it and remove the next line: " ExcludeFromSelect=* ". Then Add New hardware-> Next -> Already connected... -> Add new hardware device -> install manually -> System Device -> Have a disk (and target the machine.inf from temporal folder) -> Standar device system and choose PnP from the right list.

Then i realise after rebootin that i already have a PnP (My bad) and kaboom! I searched in google and ppl who had the same problem as i, they cant remove it and ppl suggest to use System Restore or Format.

See this series of posts. You can use the sc command from a command prompt to delete (or create) services. You can also edit the registry and remove services that way.

http://www.theelderg..._windows_xp.htm

Before doing either, install ERUNT and make a complete registry backup. That way if you do something wrong, you can easily recover. ERUNT is available here: http://www.larsheder...nline.de/erunt/

BTW: If you had ERUNT installed before doing all this, recovery would have been easy :)

Do you see any difference in the registry key" HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services

Once you have ERUNT installed and have backed up the registry, do the following:

From the command prompt, enter:

sc query > scout.txt
notepad scout.txt


In notepad, press Ctrl+f, enter plug and press Enter.
See what the Plug and Play entries look like. If they are identical then
I would delete one of them. If not then need to figure out which is which.
Post all listed data for both here.

To delete one,

sc delete plugplay

What do you see when you run sc query. Sounds to me like you may have only one then.

Just the one though, right? Sure sounds like you don't have two.
