While performing certain tasks like playing a video, or while running a program or even when you do something with your windows explorer, you might have got this dialog box saying Desktop Window Manager stopped working and was closed. You might be clueless about what happened, even choosing the option to fix the issue online wouldn’t have done any good. Of course it is frustrating to get these sort of dialog boxes as it severely tampers the user experience.
This problem mainly occurs because of some corrupt files. Other reasons vary. Read on, to learn how you can fix this problem using some very simple methods.
Method 1: Try Rotating the Second Screen
If you are using 2 monitors and if you tried changing some settings in your graphics card like rotating your second screen, then you should try rotating your second screen back to landscape mode. Once you are done with rotating the screen, please restart your machine and check if the issue persists. If you’re confused about how to rotate your second screen, please follow the steps below:
1. Right click on an empty spot in your Windows Desktop and click on the option that says Display settings.
2. Now, under the section Rearrange your displays, you will get the option to choose the Display that you want to make changes to. Click on the tab named 2 to rotate the second screen.
3. Now scroll all the way down until you find the dropdown menu by the name Display orientation. Click on the arrow associated with it and choose the option Landscape.
4. You will now be shown an alert asking whether to keep the changes or to revert them. Choose Keep changes in this step.
Method 2: Repair Damaged Windows Files by Running System Scan
One of the reasons why we get the Desktop Window Manager Stopped Working problem is because of corrupt system files. We can try repairing these damaged files by running the System File Checker (SFC) command utility. If SFC finds some issues with Windows system files, then it will try to repair these files. Follow the steps below to try this method:
1. Type in cmd in Windows Start menu search bar and from the results that appear, right click on Command Prompt and then choose the Run as administrator option.
2. When the Command Prompt opens up in administrator mode, copy paste the command sfc /scannow and hit Enter key. Please make sure that you don’t abort the process. Wait for it to finish.
After SFC scan is complete, if you get the message Windows Resource Protection found corrupt files and successfully repaired them. Details are included in the CBS.Log %WinDir%\Logs\CBS\CBS.log, that means your issue is most probably found and fixed by SFC scan. Please verify.
Method 3: Perform Windows Clean Boot
If your issue is still not resolved even after following the above 2 methods, then you can try performing a Windows clean boot. This will fix any potential issues and will even make your system run faster.
