XP MCE 2005: Based on XP Home or XP Pro?

WinInfo | at | by Mike

A lot of people are speculating that Windows XP Media Center Edition (XP MCE) 2005 is based on XP Home Edition, not on XP Professional Edition, as earlier releases were. Their reasoning is that XP MCE 2005 drops a few key XP Pro features, such as the ability to log on to a domain, Group Policy Editor (GPE), and Encrypting File System (EFS) support. But XP MCE 2005 does include many key XP Pro features, such as Microsoft Internet Information Services (IIS) 5.1. So what's the truth? Honestly, people are asking the wrong question because all XP versions are based on the same code base. The key question is why XP MCE has changed at all.
