Windows Lockscreen Configuration
At the moment it is not possible to configure the windows 10 locksreen if Safeguad is installed.
Please make it possible to let the admin choose if it is possible or not.
Best would be to configure it via Windos GPO. To configure it via Safeguard policy would be an alternative way.
If by Windows 10 Lockscreen you mean the bitmap users see when they lock their computer, then this is possible already, at least with SGN 8.1.
If not, can you specify more in detail what you mean?
