Common questions
What does the WPDBusEnum service do?
Enforces group policy for removable mass-storage devices, and enables applications such as Windows Media Player and Image Import Wizard to transfer and synchronize content using removable mass-storage devices. It runs C:\Windows\System32\svchost.exe (svchost.exe -k LocalSystemNetworkRestricted) as LocalSystem.
Can I disable WPDBusEnum?
Depends on what you use. Microsoft's guidance for fixed-purpose Windows 10 and 11 IoT Enterprise devices rates it OK to disable. If you transfer or synchronize content with removable mass-storage devices through applications such as Windows Media Player, leave it. Its default startup type is Manual: on the PC used for this page it was stopped.
WPDBusEnum is not running. Is that a fault?
Not by itself. Microsoft lists Manual as its default startup type, and on Windows 11 build 26300 the service has a trigger registered, so Windows starts it when it is needed. On that PC it was stopped.
How do I check that it is the real service?
On build 26300 it is registered as svchost.exe -k LocalSystemNetworkRestricted, runs as LocalSystem and loads C:\Windows\system32\wpdbusenum.dll, signed by Microsoft Windows. It depends on RpcSs.
