+<!--Description-->
+This policy setting prevents installation of Internet Information Services (IIS) on this computer. 
+
+- If you enable this policy setting, Internet Information Services (IIS) cannot be installed, and you will not be able to install Windows components or applications that require IIS. Users installing Windows components or applications that require IIS might not receive a warning that IIS cannot be installed because of this Group Policy setting. 
+
+Enabling this setting will not have any effect on IIS if IIS is already installed on the computer. 
+
+- If you disable or do not configure this policy setting, IIS can be installed, as well as all the programs and applications that require IIS to run."
+
+<!--/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).
