In early July 2015, Microsoft announced that the Electronic Program Guide (EPG) for Windows Media Center was being updated on July 7, 2015 with new video data packages.[27][28] This update to the EPG changed the service provider from Zap2It to Rovi. Since the update a large number of reports have been posted to the Microsoft Media Center Feedback page[29] indicating that the EPG data feed from Rovi has significant data quality issues relating to incorrect channel lineups, outdated and incorrect program data and failure to download the EPG data from Rovi through Microsoft's servers. This update was not given to the early Insider Preview builds of Windows 10 even though they included the WMC.
