 <!--/Validation-->
 <!--/Policy-->
 
+To enable this policy, use the following SyncML. This example allows Windows to install a fictitious device ID, a list of hardware IDs and a list of compatible IDs. In this example, the enumerator is specified by the GUID "{17ed6609-9bc8-44ca-8548-abb79b13781b}". The format of the vendor-specific-id field is Vendor&Device&Subsystem&Revision, where the Vendor subfield is "ven_1", the Device subfield is "dev_2", the Subsystem subfield is "subsys_3", and the Revision subfield is "rev_4".
+A device ID is the hardware ID that is the most specific description of a device. In the following example, the device ID specifies the vendor, the device, the subsystem, and the revision. This example applies to matching device IDs that are already installed. 
+
+To configure multiple classes, use `&#xF000;` as a delimiter. To apply the policy to matching device classes that are already installed, set DeviceInstall_IDs_Deny_Retroactive to true.

+To verify the policies are applied properly, check C:\windows\INF\setupapi.dev.log and see if the following is listed near the end of the log:

+```txt
