Windows 10: Desktop Window Manager causing problem

I am facing a problem related to desktop window manager or dwm.exe as it is occupying more than normal amount of ram. At times it occupies more than 500 mb ram. I have installed all the latest drivers available. I am currently using windows 10 version 20h2. Please suggest what can be done as it is very annoying. I am attaching a screenshot showing the dwm.exe process.

Please Help.

Desktop Window Manager causing sluggishness

Hi Michael,

Thank you for posting your query in Microsoft Community.

I understand that the performance of the PC is slow due to Desktop Window Manager and I will be happy to answer your query.
I would suggest you to perform following methods and check.

Method 1: Run System Maintenance troubleshooter and check if it helps.


Follow the steps:

• 
  Press Windows and X key together and select
  Control Panel.
  
• 
  Click on Troubleshooting.
  
• 
  Click on View all option on the left side of the Windows.
  
• 
  Click on System Maintenance option.
  
• 
  Click on Next and follow the onscreen instructions to troubleshoot the issue.
  

If the issue still persists, continue to the next method.



Method 2: We will check the functionality in safe mode with networking.

Step 1: Safe mode with Networking.



Safe mode is useful for troubleshooting problems with programs and drivers that might not start correctly or that might prevent Windows from starting correctly. Safe mode starts Windows with a limited set of files and
drivers. To start your system in safe mode follow the below steps:

• 
  On your lock screen, click on the power button and press
  shift + restart.
  
• 
  After that, you will be redirect to an option screen.
  
• 
  Select troubleshoot>advanced option > start up repair.
  
• 
  Follow the on screen instructions and select safe mode with networking.
  

If the issue still persists, please run a clean boot and check if the issue persists.

Step 2: Clean boot.

Putting your system inClean Boot state helps in identifying if any third party applications or startup items are causing the issue. You need to follow the steps from the article mentioned below to perform a Clean Boot.

DISCLAIMER: After troubleshooting, refer to this section "How to reset the computer to start normally after clean boot troubleshooting".

Hope this information is helpful. Please feel free to reply in case you face any other issues with Windows in future.

 

Update causes task manager problems

After logging on yesterday, I got the 'Updating Windows' message. along with the whirlygig, after it was finished the Task Manager did not function.
IF I clicked on one of the icons, nothing would happen. This also affected the window icon in the lower left corner of the screen and the icons in the lower right(speaker volume etc).

I've had hard drive problems in the past which may be the cause, but since this happened immediately after the update, I'm inclined to believe the cause was the update.

The only way I can start say Excel is to click on an Excel file on the desktop to activate excel.

Any suggestions?
