#define VER_SUITE_EMBEDDED_RESTRICTED       0x00000800

The suite mask is part of the operating system version. The complete list of suite mask constants, along with some explanation, is here. It indicates whether the version of Windows being run is an Enterprise edition, Data Center edition, home edition, etc.

VER_SUITE_COMMUNICATIONS = This is a version of Microsoft Office Communications Server

VER_SUITE_EMBEDDED_RESTRICTED = Embedded Windows (I'm not sure what the RESTRICTED indicates)
