How to delete the registry entry for the un-used disk drives

NTDEV
1

Hi all,

I am testing the management software for the RAID controller. After
creating/deleting the arrays for sometime the system starts getting more
time to boot. I think this could be due to the un-used disk registry entries
under HKLM/System/CurrentControlSet/Enum KEY. How to delete these un-used
disk entries? When tried deleting it, I am getting Erro message “Cananot
delete entry”

Please help,
Shakeel.

Hmm, how much additional time is this taking?

We have a tool called scrubber available from product support that
deletes these (and many more, there are at least seven registry
locations used for disks/partitions/volumes) using Setup API calls, but
I’ve not heard of this impacting boot time.

You can change the security permissions to allow full control using regedt32.exe (regedit.exe does not allow to do this) and delete the enum keys.

Thanks Mohan, I was able to delete it by using the regedt32.exe.

Now how to do it programmatically? Is deleting the entry in
currentControlSet\Enum would be enough?
Jeff, you said there are at least seven registry locations to delete. What
and where are these registry entries?

Thanks,
Shakeel.

For a device which belongs to MS-defined class:

  • Services\DriverName - the driver service key
  • Enum\Bus\DeviceID\InstanceID - the PnP device key
  • Control\Class\Number - the PnP driver key

Delete them and all will be fine. Deleting under Enum subtree requires
permission patching.

If the device installs a custom setup class with it, then the picture is
more complex.
