+<!--Description-->
+Available in Windows 10 Insider Preview Build 20185. Allows you to disable System Restore configuration through System Protection.
+
+This policy setting allows you to turn off System Restore configuration through System Protection.
+
+System Restore enables users, in the event of a problem, to restore their computers to a previous state without losing personal data files. The behavior of this policy setting depends on the "Turn off System Restore" policy setting.
+
+If you enable this policy setting, the option to configure System Restore through System Protection is disabled.
+
+If you disable or do not configure this policy setting, users can change the System Restore settings through System Protection.
+
+Also, see the "Turn off System Restore" policy setting. If the "Turn off System Restore" policy setting is enabled, the "Turn off System Restore configuration" policy setting is overwritten.
+
+<!--/Description-->
+> [!TIP]
+> This is an ADMX-backed policy and requires a special SyncML format to enable or disable. For details, see [Understanding ADMX-backed policies](./understanding-admx-backed-policies.md).
+> 
+> You must specify the data type in the SyncML as &lt;Format&gt;chr&lt;/Format&gt;. For an example SyncML, refer to [Enabling a policy](./understanding-admx-backed-policies.md#enabling-a-policy).
+> 
+> The payload of the SyncML must be XML-encoded; for this XML encoding, there are a variety of online encoders that you can use. To avoid encoding the payload, you can use CDATA if your MDM supports it. For more information, see [CDATA Sections](http://www.w3.org/TR/REC-xml/#sec-cdata-sect).
