-To enable this policy, use the following SyncML. This example prevents Windows from installing CD-ROM drives, floppy disks, and modems (ClassGuid= {4d36e980-e325-11ce-bfc1-08002be10318}), and storage devices that use Serial Bus Protocol (SBP-2) drivers (ClassGuid = {d48179be-ec20-11d1-b6b8-00c04fa372a7}). This policy example also applies to matching device classes that are already installed.

 Enclose the class GUID within curly brackets {}. To configure multiple classes, use `&#xF000;` as a delimiter. To apply the policy to matching device classes that are already installed, set DeviceInstall_Classes_Deny_Retroactive to true.
