Windows Desktop Manager (wdm.exe) process high RAM usage in L390

2021-04-14, 12:11 PM

Hi!

 

The Windows Desktop Manager (wdm.exe) process sometimes is using more than 1gb to 1.5 gb of RAM, making my laptop to overheat.

I have a Thinkpad L390. Everything is updated.

How can I fix this problem? It is a problem with the graphics driver?

 

Thanks

Hello DanielCV,

 


Welcome to Lenovo Community

 

 

Desktop Window Manager (DWM, previously Desktop Compositing Engine or DCE) is the window manager in Windows Vista, Windows 7, Windows 8 and Windows 10 that enables the use of hardware acceleration to render the graphical user interface of Windows.

It was originally created to enable portions of the new "Windows Aero" user experience, which allowed for effects such as transparency, 3D window switching and more. It is also included with Windows Server 2008, but requires the "Desktop Experience" feature and compatible graphics drivers to be installed

I suggest that you update the BIOS and drivers thru the support site.
Next step is to run the system file checker (both SFC scannow and DSIM).
Update us how it goes

 


Regards, 
Lorenzo_Lenovo

Hello, Lorenzo, thanks for your reply.

 

I checked for updates on the support page. Everything is up to date. Version BIOS: LENOVO R10ET48W (1.33 ), 13/01/2021.

All the other drivers are up to date too.

After that, I went on with the suggested verification. Apparently everything is fine.

 

Here are the results. 

 

C:\Windows\system32>DISM.exe /Online /Cleanup-image /Restorehealth

Ferramenta de Gerenciamento e Manutenção de Imagens de Implantação
Versão: 10.0.19041.844

[==========================100.0%==========================] Operação de restauração concluída com êxito.

Iniciando fase de verificação de verificação do sistema.
Verificação 100% concluída.

A Proteção de Recursos do Windows não encontrou nenhuma violação de integridade.

 

The problem is still there.

You can try to check how the RAM goes when the machine is running in safe mode.
Otherwise, set Windows to clean boot just in case other processes might be triggering this behavior, before deciding on full reset.
Running diagnostics can also help to isolate hardware issue just in case.
Hope this helps

Thanks for the update.
It seems that there are programs causing high RAM usage even in clean boot.
Kindly back up your files before doing a full reset

Hello, I am also experiencing this problem, using an l390 with an external monitor. As it seems, there's a memory leak problem around dwm.exe and the intel display driver. I have already tested it with several drivers from both Lenovo's and Intel's sites. including the latest and some older versions. Someone reported the 24.20.100.6290 driver, which is some two years old, is not exhibiting this problem for him (although with the UHD630 video system, which is not exatly the same as the UHD620 found in the L390): https://community.intel.com/t5/Graphics/BUG-dwm-exe-uses-memory-leakage-with-Intel-HD-Graphics-630/m-p/1222297 This older driver, however, can no longer be found on Lenovo's webpage (or Intel's, for a matter of fact). If someone has a download link for this older driver, I'd happily test if the problem is present with it or not. Lenovo support, can you find this older driver for me please?

you tried those ? 
2019-1-4     24.20.100.6346     IntelVideo-r10d204w.exe     
2019-1-4     25.20.100.6471     IntelVideo-r10d206w.exe

 

none of those versions work?

as far i can tell those are the oldest releases for that specific lenovo laptop (by lenovo)

 

google XPS-8930_Intel-UHD-Graphics-Driver_20R37_WIN_24.20.100.6290_A00.EXE

 

but i don't know if that brand made specific changes to the driver....
