What Is Dwm.exe Windows Xp
The desktop itself is a full-screen Direct3D surface, with windows being represented as a mesh consisting of two adjacent (and mutually-inverted) triangles, which are transformed to represent a 2D rectangle. The texture, representing the UI chrome, is then mapped onto these rectangles. Window transitions are implemented as transformations of the meshes, using shader programs. With Windows Vista, the transitions are limited to the set of built-in shaders that implement the transformations. Greg Schechter, a developer at Microsoft has suggested that this might be opened up for developers and users to plug in their own effects in a future release. DWM only maps the primary desktop object as a 3D surface; other desktop objects, including virtual desktops as well as the secure desktop used by User Account Control are not.

The Desktop Window Manager uses Media Integration Layer (MIL), the unmanaged compositor which it shares with Windows Presentation Foundation, to represent the windows as composition nodes in a composition tree. The composition tree represents the desktop and all the windows hosted in it, which are then rendered by MIL from the back of the scene to the front. Since all the windows contribute to the final image, the color of a resultant pixel can be decided by more than one window. This is used to implement effects such as per-pixel transparency. DWM allows custom shaders to be invoked to control how pixels from multiple applications are used to create the displayed pixel. The DWM includes built-in Pixel Shader 2.0 programs which compute the color of a pixel in a window by averaging the color of the pixel as determined by the window behind it and its neighboring pixels. These shaders are used by DWM to achieve the blur effect in the window borders of windows managed by DWM, and optionally for the areas where it is requested by the application.
Since MIL provides a retained mode graphics system by caching the composition trees, the job of repainting and refreshing the screen when windows are moved is handled by DWM and MIL, freeing the application of the responsibility. The background data is already in the composition tree and the off-screen buffers and is directly used to render the background. In pre-Vista Windows OSs, background applications had to be requested to re-render themselves by sending them the WM_PAINT message. DWM uses double-buffered graphics to prevent flickering and tearing when moving windows. The compositing engine uses optimizations such as culling to improve performance, as well as not redrawing areas that have not changed. Because the compositor is multi-monitor aware, DWM natively supports this too.
For applications using DirectX to write to a 3D surface, the DirectX implementation in Windows Vista uses WDDM to share the surface with DWM. DWM then uses the surface directly and maps it on to the window meshes. For Windows presentation foundation (WPF) applications (which are DirectX applications), the compositor renders to such shared surfaces which are then composited into the final desktop. Applications can mix either rendering technique across multiple child windows, as long as both GDI and DirectX are not used to render the same window. In that case, the ordering between DirectX and GDI rendering cannot be guaranteed, and as such it cannot be guaranteed that the GDI bitmap from the system memory has been translated to the video memory surface. This means that the final composition may not contain the GDI-rendered elements. To prevent this, DWM is temporarily turned off, as long as an application which mixes GDI and DirectX in the same window is running.
Desktop Window Manager files, such as dwm.exe, are considered a type of Win32 EXE (Dynamic link library) file. They are associated with the EXE file extension, developed by Microsoft for Microsoft Windows Operating System.
The first version of dwm.exe was released for the Windows Vista Operating System on 11/08/2006 inside Windows Vista. On 07/29/2015, version 10.0.15063.0 (WinBuild.160101.0800) was released for Windows 10. Dwm.exe is found in Windows 10, Windows 8.1, and Windows 8.
Runtime errors are Windows errors that occur during "runtime". Runtime is pretty self-explanatory; it means that these EXE errors are triggered when dwm.exe is attempted to be loaded either when Windows is starting up, or in some cases already running. Runtime errors are the most common form of EXE error you will encounter using Windows.
In most cases, dwm.exe runtime errors occurring while the program is running will result in the program terminating abnormally. Most of these dwm.exe error messages mean that Windows was either unable to locate this file on startup, or the file is corrupt, resulting in a prematurely-aborted startup process. Generally, Windows will be unable to start without resolving these errors.
Finding the source of the dwm.exe error is key to properly resolving these errors. Although most of these EXE errors affecting dwm.exe will happen during startup, occasionally you will encounter a runtime error while using Microsoft Windows Operating System. This can occur due to poor programming on behalf of Microsoft Corporation, conflicts with other software or 3rd-party plug-ins, or caused by damaged and outdated hardware. Also, these types of dwm.exe errors can occur if it has been accidentally moved, deleted, or corrupted by a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.
System File Checker is a utility included with every Windows version that allows you scan and restore corrupted system files. Use the SFC tool to fix missing or corrupt dwm.exe files (Windows XP, Vista, 7, 8, and 10):
When the first two steps haven't solved your issue, it might be a good idea to run Windows Update. Many dwm.exe error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:
If none of the previous three troubleshooting steps have resolved your issue, you can try a more aggressive approach (Note: Not recommended for amateur PC users) by downloading and replacing your appropriate dwm.exe file version. We maintain a comprehensive database of 100% malware-free dwm.exe files for every applicable version of Windows. Please follow the steps below to download and properly replace you file:
GEEK TIP : We must emphasize that reinstalling Windows will be a very time-consuming and advanced task to resolve dwm.exe problems. To avoid data loss, you must be sure that you have backed-up all of your important documents, pictures, software installers, and other personal data before beginning the process. If you are not currently backing up your data, you need to do so immediately.
CAUTION : We strongly advise against downloading and copying dwm.exe to your appropriate Windows system directory. Microsoft typically does not release Windows EXE files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing dwm.exe and all other EXE files for Windows. An incorrectly installed EXE file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
Windows users who do not know about processes in detail often think that dwm.exe is a virus. More often than not, this is thanks to issues with the file consuming a large number of resources and slowing down your computer.
Some users have noted situations where Desktop window manager high CPU or Desktop windows manager high memory. This is a common error, especially in Windows 10. You can turn the Desktop Window Manager off or on through the Control Panel.
To ensure that no malicious dwm.exe is running on your PC, you need to scan your PC with quality antivirus software. Here at SoftwareKeep, we provide access to a variety of antivirus applications capable of detecting and disabling any virtual threat.
The dwm.exe CPU usage increases as you open more Windows programs, sometimes using several megabytes, which is normal. If you notice the Desktop window manager high CPU after closing most programs, you may need to take action.
If you are using Windows Vista, you could disable dwm.exe, which will, in turn, turn off all the Windows visual effects (in Windows Vista. The process, however, becomes a more integral part of Windows, beginning with Windows 7, and disabling it on any OS beginning with Windows 7 can affect your graphical user interface.
Disabling the dwm.exe service is not recommended or possible on systems released after Windows Vista. Because of this, troubleshooting errors and high resource usage related to the process requires different methods.
If the dwm.exe is using high CPU power or memory, it might be due to malware such as computer viruses, hidden crypto-currency miners, and spyware. In this case, you must use an antivirus application to scan your device and detect threats.
The problem may be caused by a legitimate program that disrupts the Aero display, such as a program that is linked to themes or adds effects to Windows windows. Second, it may be that the graphics settings are too greedy for configuration, or that the graphics card drivers are not installed.
dwm.exe produces memory leak with 6th Generation Intel processors through 10th Generation Intel processors. The dwm.exe memory usage starts low (30MB), accumulates over time, and may result in a system crash. 041b061a72
