The Echo is compatible with Windows Media Center on Windows 7 today. Unfortunately, Microsoft made changes in Windows 8 that result in all non-Microsoft extenders being incompatible with Windows 8 PCs. We have investigated alternative ways of being able to use Echo with Windows 8 systems but none have worked out. At this point we have no plans to support the Echo when used with Windows 8 PCs unless Microsoft makes changes in Windows, which we do not expect.
