This is again not quite new, but needs to be added here for the sake of completeness 🙂
One of the first customizations of Windows 10 in the enterprise is probably to turn off app recommendations by Microsoft. This new feature displays suggested apps in the start menu like the good old Candy Crush Jelly Saga.
It can be turned off by group policy, MDM policy or registry. When you create a reference image, keep in mind that the reference client should not be connected to the internet. By the way, this is generally not recommended.
The group policy setting can be found here: Computer Configuration – Administrative Templates – Windows Components – Cloud Content: Set “Turn off Microsoft consumer experiences” to Enabled.
The MDM policy is documented here: https://msdn.microsoft.com/en-us/library/windows/hardware/dn904962(v=vs.85).aspx#Experience_AllowWindowsConsumerFeatures
To configure it via registry, set the REG_DWORD value “DisableWindowsConsumerFeatures” to “1” here: HKLM\Software\Policies\Microsoft\Windows\CloudContent.
