+<!--Description-->
+This policy controls the inclusion of Edge tabs into Alt+Tab.
+
+Enabling this policy restricts the number of Edge tabs that are allowed to appear in the Alt+Tab switcher. Alt+Tab can be configured to show all open Edge tabs, only the 5 most recent tabs, only the 3 most recent tabs, or no tabs. Setting the policy to no tabs configures the Alt+Tab switcher to show app windows only, which is the classic Alt+Tab behavior. 
+
+This policy only applies to the Alt+Tab switcher. When the policy is not enabled, the feature respects the user's setting in the Settings app.
+<!--/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).
