One example of a command line restart is here (for Windows 8, but applicable for 10 too): I’ve found a good way to reset DWM.exe when this happens. Many people don’t realize the memory leak is occurring and when the computer gets slow, they just restart it. Some newer firmware seems to have the issue, the older Intel firmware doesn’t. I did some research and it seems this is indeed an Intel chipset issue that is plaguing many new Windows 10 machines. Which then defeats the purpose of having two screens. The ONLY solution I’ve found is to not put the ATC window on the second screen. I change nothing, boot up the next day with all the same settings and same running software, and it will chew through gigabytes of memory. Some days I can fly with the ATC window on my second monitor and DWM will sit happily at 108mb the whole flight. The real kicker is that it doesn’t always have this issue. Seems like a common problem, but no clear answers. Contacted Microsoft (they had me do the same basic things I’ve already done) Contacted laptop manufacturer (they had no idea) Changing Virtual Memory Paging size to recommended size vs. Running MS System File Checker (sfc scannow) Running full virus scan with my A/V and from Eset online Updating Nvidia drivers from 456.xx to 460.89 Updating windows from version 2004 to 20H2.

I have tried the following to remedy this. I have two screens, so why not put that window on the second one, I thought… Well…I guess it causes problems. I did some investigating and found it’s ONLY MFSF2020 that causes this, and only when the ATC window is on my second monitor.

Once quitting MSFS2020, it does not continue to climb, but also will not go back down. I flew for 45 minutes the other day, and it had 7 GB (yes, GB, not MB) of memory used for DWM. The problem is the Desktop Window Manager (DWM, as seen in the processes tab of task manager) will pretty rapidly (within 10-15 minutes) climb from a normal 108-200 mb of memory usage, to insane percentages of memory. Windows 10 is at 20H2 update, and all firmware and software up to date.

I have a brand new gaming laptop, with an i7-10750 6-core CPU, 32 GB DDR4 ram, and Nvidia RTX 2060 GPU with 6bg of memory. Hopefully someone can shed some light on it. I’m at wits end with an annoying problem.
