How to disable SSL 2.0 and 3.0

I have disabled SSL 2.0 and 3.0 on a Windows 10 PC in our environment as described in the articles linked below, but for some reason this PC is still being flagged by our security software (Nessus) for SSL 2.0 and 3.0.

I looked at the PC again and verified that the registry keys are still set correctly. With SSL disabled in the registry in this way, is it even possible for anything on the computer to turn on or otherwise use SSL 2.0/3.0? My understanding is that any application that needs it will simply stop working.

Thanks in advance,
