FIGURE 15-6 If you don’t want your users installing preview builds of Windows 10, set this policy.
Setting Toggle User Control Over Insider Builds to Disabled removes the option for users to get
preview builds. Note that this policy setting applies only to devices running the Pro, Enterprise, and
Education editions of Windows 10.
The Allow Telemetry setting, also in this group, creates a fourth option that minimizes the amount
of data sent to Microsoft as part of its normal diagnostic and usage data-collection policy. (The other
three options are located in Settings, Privacy, Feedback & Diagnostics.) This minimal setting sends only
data from the Malicious Software Removal Tool and Windows Defender (if enabled), as well as settings
for the telemetry client.
Managing Windows Update Delivery Optimization
By design, Windows 10 creates a peer-to-peer delivery system that helps spread the load of delivering
Windows apps and updates. In a managed environment, you might prefer to restrict this peer sharing
to devices that are on the same local network or domain. You might also want to exercise control over
the amount of upload bandwidth this feature can use.
These and other policy settings are available under Computer Configuration > Administrative
Templates > Windows Components > Delivery Optimization. Confusingly, the Help text for this setting
specifies numeric values (0 through 3, with a setting of 0 disabling the feature), while the actual
interface for changing this setting in the Group Policy editor uses a drop-down list whose entries
correspond to those numeric values, as shown in Figure 15-7.
