Containing all features from Home Basic and similar to WinXP MCE, this edition also supports additional features aimed for the home market segment, such as support for HDTV and DVD-authoring. It also includes games, support for mobile and tablet PCs, for network projectors, for touchscreens, and for auxiliary displays (via Windows SideShow), and a utility to schedule backups. Home Premium supports 10 simultaneous SMB peer-network connections (compared to 5 in Home Basic). The version of Meeting Space included also allows for interaction (in Home Basic, one may only view meetings). This edition has functionality comparable to that of Windows XP Media Center Edition. Like Home Basic, it supports only one physical CPU, but multiple cores. 64-bit Home Premium supports up to 16 GB of RAM.
