In this release, we've improved Windows 10 device self-enrollment using proxy settings and fixed defects to solve some usability issues. This enables the device self-enrollment in a full proxy environment and minimizes network bandwidth required to download the client during enrollment.
Leverage proxy settings for self-enrollment of Windows 10 devices
To support self-enrollment on Windows 10 devices that are operated in a full proxy environment, we have added support for additional configuration settings. These settings are required to communicate with the SEP Cloud client and use the proxy settings that are configured in a system policy.
