<P> Windows Media Center was discontinued, and is uninstalled when upgrading from a previous version of Windows . Upgraded Windows installations with Media Center will receive the paid app Windows DVD Player free of charge for a limited, but unspecified, time . Microsoft had previously relegated Media Center and integrated DVD playback support to a paid add - on beginning on Windows 8 due to the cost of licensing the required DVD decoders, and the increasing number of PC devices that have no optical drives . </P> <P> The OneDrive built - in sync client, which was introduced in Windows 8.1, no longer supports offline placeholders for online - only files in Windows 10 . This functionality was re-added in Windows 10 version 1709, under the name "OneDrive Files On - Demand". </P> <P> Users are no longer able to synchronize Start menu layouts across all devices associated with a Microsoft account . A Microsoft developer justified the change by explaining that a user may have different applications they want to emphasize on each device that they use, rather than use the same configuration across each device . The ability to automatically install a Windows Store app across all devices associated with an account was also removed . </P> <P> Web browsers can no longer set themselves as a user's default without further intervention; changing the default web browser must be performed manually by the user from Settings' "Default apps" page, ostensibly to prevent browser hijacking . </P>
