More info?)
the problem now is all the PnP devices that are added into the registry
under System/CurrentControlSet/Enum. If you are comfortable removing the
keys the PnP function creates the keys as system. Since you are
administrator on the system you do not have access to delete the keys (by
default). The good thing is since you are administrator you can right click
on the key, select Permissions from the menu, and add machine\administrators
to the key and grant full control. Then you can delete the key referenced
in the MS KB article.
