At issue: Windows 7 Ultimate (RTM build) Windows Media Center runs fine when logged in as Administrator. TV works great. When I login with my (account) WMC won't run, MS error says - you are currently logged on as guest. Windows media center requires a non-Guest account. My account has all privleges and Administrator rights. My account member of all 'groups'. Guest Account is currently turned off. WTF? Anybody know what the trick is to get WMC to run, when logged on as an administrator level account with all rights? Gotta be a trick for this (bug?) Thanks!
