2 questions regarding the release notes of SEP 12.1. RU2

I just read the Symantec™ Endpoint Protection, Symantec Endpoint Protection Small Business Edition, and Symantec Network Access Control 12.1.2 Release Notes and stumled over two things to clearify:

1. Symantec Endpoint Protection 12.1.2 does not support Windows To Go (2868431) - There is no workaround

Does that really mean you have to decide wether you install SEP or using Windows To Go?

2. Windows Server 2012 Essentials is not mentioned in the supported plattform section, neither for SEP 12.1 RU2 EE nor for SEP 12.1. RU2 SBE

Does that mean that Windows Server 2012 Esssentials is still not supported by RU2?
