Desktop Window Manager Service on Windows 7 Starter - Any Reason to Leave It Running?

Question

Hello everyone,
-As per title, I'd like to know whether is it better to turn off Desktop Window Manager Session Manager (UxSms) service on Windows 7 Starter - or not. I mean changing the service's default startup type from Automatic to Manual (or Disabled).
-In Windows 7 Starter, the Aero theme and desktop composition are not available at all (not even a basic/partial one), so letting Desktop Window Manager (DWM.exe) to continuously run is useless as it does absolutely nothing. Is my deduction correct?
-All opinions and suggestions are welcomed, thank you very much.
Regards,
-Musafir_86.

Desktop Window Manager
The desktop composition feature, introduced in Windows Vista, fundamentally changed the way applications display pixels on the screen.  When desktop composition is enabled, individual windows no longer draw directly to the screen or primary display
device as they did in previous versions of Windows. Instead, their drawing is redirected to off-screen surfaces in video memory, which are then rendered into a desktop image and presented on the display.
Desktop composition is performed by the Desktop Window Manager (DWM).  Through desktop composition, DWM enables visual effects on the desktop
as well as various features such as glass window frames, 3-D window transition animations, Windows Flip and Windows Flip3D, and high resolution support.
The Desktop Window Manager runs as a Windows service. It can be enabled and disabled through the Administrative Tools Control Panel item, under Services, as Desktop Window Manager Session Manager.
Many of the DWM features can be controlled or accessed by an application through the DWM APIs.  The following documentation describes the features and requirements of the DWM APIs.
