remove registry entries under Enum in Win2k

Hi,

Can any body tell me how to remove registry entries under
local_machine\currentControlSet\Enum in Win2k? Looks win2k has some security
stuff and doesn't allow an app to remove some registries as easy as in
Win9x.

thanks

    You must use regedt32.exe and change the security permission before you can make
    any changes.

    From what I understood, there should be no reason why you need to delete
    these keys.

    What do you want to delete registry entries under the \enum key?

    For those registry entries added by your program. You could use a
    Co-Installer ( Documented in the DDK ) to manually delete the entries
    created by your install program. The Co-Install uses API calls that have
    sufficient privileges.

    KeithGa,

    Thanks for the help.

    The reason I am doing this is that sometimes users would screw up the system
    and need some tools to clean up.

    Well if you're developing pnp products, the only documented procedure for
    cleaning up the enum key is to do a clean install of NT, which is a bit of
    overkill when you really just want to clean out cruft left by your earlier
    attempts to get things right.

    I learned that you need only change the security on the Enum Key itself, and
    that in turn cascades down throughout the subtree. Works for me.

    While we're on the subject, does anyone know what the 'Enum' key is for.
    What does it do, why is it there?

    A PnP device list.

    But there are services in there as well as devices. What does PnP have to
    do with services?

    Is there any MS documentation on the Enum key anywhere?

    Simon.

    This was a legacy from some very strange elements of PnP in NT4.
    No services in Enum on Win98.

    > Is there any MS documentation on the Enum key anywhere?

    No. But - IoOpenDeviceRegistryKey() for PLUGPLAY_REGKEY_DEVICE
    will open the key under the Enum.
    The syntax is Enum\enumerator\device\instance - this is a device registry
    key.
