Is there a sanctioned way to remove a Device Class?

NTDEV

I cannot seem to find reference to a mechanism for removing a device class
(the opposite of having the [ClassInstall32] section of an INF run
automatically). Is there such a mechanism?

And by ‘sanctioned’ I mean that the Setup APIs are involved in a way that
keeps the class database ‘consistent’. I am aware and familiar with the
two big-hammer mechanisms of “re-install O/S” and “regedit brute-force
delete of the Class/ key”.

Thanks,

AFAIK, no. The idea is that once a class is installed, it is there forever, it is not something you can revert later.

And by ?sanctioned? I mean that the Setup APIs are involved in a way that keeps the class database ?consistent?. I am aware and familiar with the two big-hammer mechanisms of ?re-install O/S? and ?regedit brute-force delete of the Class/ key?.
