First, you need to know what dwm.exe is and what it is used for. DWM stands for Desktop Windows Manager, an essential process that is used to render the graphical user interface by Windows. If you try to disable DWM or it stops working, some Windows and application processes will not run and may get crash. Moreover, when you try to end task DWM, it won’t shut down, and when you open the task manager, you will see that the DWM process is still running.
Desktop Windows Manager has a .exe extension, which means it is an executable system file used for the system. All the system files are located in Windows 32. Therefore, before troubleshooting, ensure the DWM is located in Windows>system32. If it’s not there, your Windows may be affected by the virus/trojan.
