High Memory usage by Desktop Window Manager on Windows 11 on Dell G5 5590

There is a bug in Windows 11 as mentioned here which may be the cause of your memory usage. The details are here and apparently in the dev channel insider's build it has been fixed. That fix should be in an update shortly according to sources.

May be, Thank you*

Happy to help out!

me too

Thanks, bro, let me try. But it's frustrating that dell is not releasing updates for graphic drivers.

I share your frustration! But the latest Intel production driver (as of today) also exhibits the problem. I'd like to say this beta driver nails it, but I've been running it less than a day. (Also -- on my system Windows sometimes loaded the old driver at boot time even after I'd installed the new one. I had 3 different drivers available and t seemed to be a toss-up which one I'd get after a given boot. I ended up booting to safe mode, deleting all the Intel drivers from Device Manager -- until it was running the Microsoft Basic graphics driver -- and reinstalling the new beta driver, to insure it got loaded every time.) Fingers crossed!

It almost worked for me. Memory leak reduced to MBs from 3-5 GB Thanks bro.

FYI, Intel has released an official (generic) driver with the DWM fix. Notes here.

Hi. I have the same problem. But when I try to install the driver you have given, it does not install. It gives the following error,

My laptop details are as under,

• Model: Dell Inspiron 5570
• Windows 11 Home 64-bit
• Intel Core i7 @ 1.80GHz (Kaby Lake-U/Y 14nm Technology)
• 8GB RAM
• Intel UHD Graphics 620 (Dell)
• 931GB Seagate ST1000LM035-1RK172 (SATA )
• 119GB SanDisk X400 M.2 2280 128GB (SATA (SSD)) - Windows installed on this SSD.

This problem was not present with Windows 10. It has started after the Windows 11 Update.

Plus I also feel that my PC has not remained as snappy as it used to be with windows 10. Like when I double click a folder, when I right click to open that popup list etc., I feel a little delayed response. Back in Windows 10, everything was snappy.

Any fix?

OK, keep in mind that I'm feeling my way here, same as you. (My only experience with this is my own system, and poking around trying to find the solution.)

You haven't specified your CPU exactly, but I'm guessing it's i7-8550U. Intel has now released a production generic driver containing the DWM fix, 30.0.101.1191, available here, which I think is applicable to your CPU (but perhaps not your laptop? read on). On that page they also link to a troubleshooting page here with instructions on solving installation errors. Basically you uninstall any existing drivers until Device Manager lists only Microsoft Basic Display Adapter, then install the new driver. From what I can see online, there's a good chance this procedure will solve your installation problem.

That said, Intel warns that replacing an OEM driver like Dell's with their generic driver could cause problems with some systems, and that you should (except for troubleshooting) always defer to the manufacturer's driver. Laptops tend to be a lot more custom than desktops, so I would expect that Dell has included system-specific customizations. I noticed too that the driver rev on the Inspiron 5570 support page is different from the one for my Vostro desktop (and older besides), so I imagine there are specific tweaks. You might not detect any difference, or it might be a major problem or anything in between.

I'm not sure whether Windows Update might subsequently try to reinstall the older, Dell-specific driver over the new one. I've seen this on my system and it possibly could cause problems for you, including the return of the DWM memory leak. On the other hand, the troubleshooting instructions hint that Windows Update might install the necessary customizations for proper operation and still leave the fix intact. It's hard to know without trying it. Just get good backups before you proceed, I guess. Hopefully Dell updates their driver for your system soon to include the fix.

Hope this helps!

I clearly specified my cpu. check my thread.

Sorry jobin481g... I was trying to reply to S.A.M.1992's post further down the thread, and I guess I just made a generic post rather than a reply. I think the board doesn't always display posts in chronological order either, but sorry for the confusion.
