The dwm.exe process is responsible for a variety of window manager functions within newer versions of Microsoft Windows ( Vista, Windows 7, Windows 8). The primary functions it provides are the ability to have transparent windows, visual alt-tabbing, and live taskbar thumbnails. Since these processes can be memory intensive, this file may display error messages or memory alerts. Possible causes of Dwm.exe errors These errors are frequently caused by conflicts with the file or installation profile, misuse of the file or respective directories, or a malicious attack on the system. When conflicts arise on the profile or with the file, the application may be unable to transmit data between the necessary files. When a file or directory is misused or damaged, the application as a whole may be unable to load. Malicious attacks or infections on the system may render the entire system frozen or unable to perform any necessary computing functions.
