In Windows 8 and Windows RT scheduling for Windows Updates installation was moved to the universal Maintenance Activity scheduling. The goal of moving of Windows Update activities to the Automatic Maintenance is to combine all background maintenance activity in Windows and help third-party developers add their maintenance activity to Windows without negatively impacting performance and energy efficiency.
