Dwm.exe stands for a core Windows 10 process called Desktop Window Manager. Even though this is an important process, many users reported issues with dwm.exe on Windows 10.

Users oftentimes experience crashes while gaming, once or more times a day. The screen or screens go black, although the sound is not affected.

Indeed, the system sometimes recovers by itself. However, there’s an underlying cause for the issue and you should investigate more.

What causes dwm.exe errors and how does that affect your PC?

• Malware or widespread virus infections
• Failing hardware components
• Corrupted or outdated drivers
• Incompatible or conflictual software/firmware interactions

Now, any of these factors can potentially trigger a dwm.exe crash. But there is more to it. Other common manifestations include:

• dwm.exe causing black screen
• dwm.exe causing CPU spikes (The Desktop Window Manager high memory issue may be caused by a recent Intel driver bug)
• GPU drivers acting erratically
• Random or multiple DWM notification windows

You can also choose to run a specialized app such as the Divvy Window Manager instead, but we’re also going to show you how to fix the issues.

How can I fix DWM.exe issues in Windows 10?

1. Update the controller firmware

Many gamers have been complaining about frequent crashes after installing a new Xbox controller. So what you should do is download the Xbox Accessories app from the Microsoft Store.

Install any available firmware updates you can find and relaunch your game to see if the issue reoccurs.

Replacing the controller has also worked for a few users. Or, in case you have a USB-connected controller, unplug it and see if the error persists.

2. Check your computer for malware

If dwm.exe is using too much CPU power or memory, it might be due to a computer virus.

Users reported that after scanning their computer and removing all the suspicious files the problems with dwm.exe were fixed, so be sure to try that.
