Portable Device Enumerator Service

The Portable Device Enumerator Service (WPDBusEnum) enforces Group Policy settings for removable mass-storage devices. It enables applications such as Windows Media Player and Image Import Wizard to transfer and synchronize content by using removable mass-storage devices. This service enables you to specify which portable storage devices are allowed to be connected to systems that are managed with Group Policy.

This service is installed by default in Windows 7 and Windows Server 2008 R2, and its startup type is Manual.

When the Portable Device Enumerator Service is started in its default configuration, it logs on by using the Local System account.

The Portable Device Enumerator Service is dependent upon the following system components:

  • Remote Procedure Call (RPC)
  • DCOM Server Process Launcher
  • RPC Endpoint Mapper
