In Windows 8.1 this setting was called Start Screen Layour

Specifies the Start layout for users.

This setting lets you specify the Start layout for users and prevents them from changing its configuration. The Start layout you specify must be stored in an XML file that was generated by the Export-StartLayout PowerShell cmdlet.
To use this setting, you must first manually configure a device’s Start layout to the desired look and feel. Once you are done, run the Export-StartLayout PowerShell cmdlet on that same device. The cmdlet will generate an XML file representing the layout you configured.

Once the XML file is generated and moved to the desired file path, type the fully qualified path and name of the XML file. You can type a local path, such as C:\StartLayouts\myLayout.xml or a UNC path, such as \\Server\Share\Layout.xml. If the specified file is not available when the user logs on, the layout won’t be changed. Users cannot customize their Start screen while this setting is enabled.

If you disable this setting or do not configure it, the Start screen layout won’t be changed and users will be able to customize it.

This policy setting determines whether users can access the preview build controls in the Advanced Options for Windows Update. These controls are located under "Choose how preview builds are installed," and enable users to make their devices available for downloading and installing Windows preview software.

A value of 2 sends full health and performance information. A value of 3 sends the same data as a value of 2, plus additional diagnostics data, such as the system state at the time of a hang or crash, and the files and content that may have caused the problem.

Enable this policy setting if you want the feedback option to be unavailable.
