Windows 10 Enterprise - CPUS problem

[Ernesto Messina]

I'm having a problem trying to detect a Credential Provider Usage Scenario, it is the Unlock scenario (message CPUS_UNLOCK_WORKSTATION).

On Windows 10 Professional edition my Credential Provider works, because I receive the CPUS_UNLOCK_WORKSTATION message, but on Enterprise I just receive CPUS_LOGON.

Of course it scenario is available on on Windows Vista and later, including Windows 10 Professional, but it is not working on the Enterprise edition.

Is it a bug or something like that? Was it disabled for the Enterprise edition?

Thanks in advanced
Ernest
