I am running XP Pro and there is an "unknown device" in
the list of System Devices. Windows won't let me
uninstall it and the properties tells me nothing about
what the device is. When I try to click on propetties I
get"Windows could not load the installer for System.
Please contact your hardware vendor for assistance". It
does not show anything wrong with it i.e. there are no
yellow flags with exclamation point. Any ideas of how to
get rid of it? or find out exactly what it is? Thanks.
 
Hi Roger,

To remove Unknown or Other Devices: You can delete the non-present devices
from registry. To determine the hardware key of the device:

Go to Start/Run/CMD. At the command prompt, type the following commands and
press enter after each line:

set DEVMGR_SHOW_DETAILS=1
set DEVMGR_SHOW_NONPRESENT_DEVICES=1
start devmgmt.msc

Click the View menu and select Show hidden devices. Right click the device
you want to delete and click Properties. Click the Details tab.

Select Device Instance ID. The value of Device Instance ID is the hardware
key of the device.

Example, if you see the value is Root\Image\0000, the full hardware key is:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\Image\0000

Then go to Start/Run/Regedit and navigate to the key. The data of the
Driver value is the software key of the device. Delete both the hardware
key and software key.

Kelly, thanks so much. Your suggestion was right on.
Except when I went to regedit and located the device
(ROOT\RDPDR\0000) I could not delete the Driver (REG-SZ)
{4D36E...) I thus did not try to delete the Hardware ID
for fear it could cause a problem. Any further help??
Thanks again.
