How to disable dwm.exe or stop from the startup
What is dwm.exe
Desktop Window Manager (DWM). That enables the use of hardware acceleration to render the graphical user interface of Windows. The main focus of the DWM is the enabling of the Windows Aero theme and user interface. Things such as page flips, window translucency, window resizing, and various animations come to life with a vibrancy and smoothness previously unable to earlier editions of Windows. This is all performed by a process known as desktop composition. The subsystems that compose the dwm.exe utilize a persistent shared resource in a graphic card’s memory that retains updated display information so that each Windows application no longer has to keep track of how its particular display requirements interact with other programs and Windows itself.
This of course further reduces overall CPU load. While DWM requires programs to be written to make best use of it, older DWM-agnostic programs that normally write directly to the screen employing system RAM can still be used by redirecting their respective output to DWM buffers, though the system’s CPU suffers a performance hit to accomplish this.
System requirements for DWM to work effectively include a fairly modern graphics card or processor that supports DirectX 9.0, Pixel Shader 2.0, and Windows Driver Display Model (WDDM). The graphics system should also have a minimum of 128 MB RAM and support 32 bits of information per pixel. As well, the computer itself should have at least a 1 GHz processor with 1 GB of system memory.
How to disable dwm.exe or stop from the startup follow the steps below.
- Press “Windows Key + “R” . For Run command.”
- And type in “services.msc”. This will open the services manager utility. (You may be asked by Vista’s overprotective User Account Control to enter your administrator password. Simply do so and continue.)
- In the Services Scroll down the menu to the label “Desktop Window Manager” аnd double-click Desktop Windows Manager.
- In the Desktop Windows, Manager window click Stop to disable the service. If you want to disable this process, or never startup change the Startup type from Automatic to Disabled.
NOTE: Assuming you followed the steps above accurately, the Desktop Window Manager Service has now stopped. The Windows Aero graphics will cease to function, but your PC will run much faster due to the memory and processing time released by ending the service.
If you like to re-enabling again dwm.exe
The Desktop Window Manager Service can be restarted by following the steps above and re-enabling it. Until then, however, more system resources have been made available for other, more important applications – rather than being wasted on pretty effects.
