The SCEP client can block in-place upgrade to Windows 10 due to incompatibility, and must be removed from a device before performing an in-place upgrade to Windows 10.

However, previous Windows operating systems installed the System Center Endpoint Protection (SCEP) client with the Configuration Manager client. A management client for Windows Defender is also installed automatically if the Configuration Manager client is installed. Beginning with Windows 10 and Windows Server 2016, Windows Defender is already installed.
