Desktop Windows Manager using absurd amount of RAM

So I’m pretty new to having a computer, and I have no idea what’s happening. I was looking to increase my download speeds and I looked at my RAM and I discovered that most if it was being used, even though I only had one thing open. I clicked on it to see what was using so much, and desktop windows manager was using around 2500 megabytes of ram. After doing some research, I realized this was NOT normal. I tried adjusting my settings, and doing a ton of things that websites suggested, but nothing. Still using the same amount of ram. Anyone know what’s going on?

    Hi,
    What's your system version? Please type "winver" in Search Bar to check the OS build.
    Firstly, I suggest that you could try to check for update. If any security updates could be found, install them to check.
    Then perform a clean boot.

    Meanwhile, my first consider would be iGPU and dGPU drivers. Please try to upgrade or install an older video card driver from the manufacturer's official website to check.
    Hope this helps and please help to accept as Answer if the response is useful.
    Best Regards,
    Carl

    Go to System in the Control Panel. Click Advanced system settings at the bottom on the left. Click on the Setting button for Performance. What do you see in the Visual Effects tab?

    Are you using the Task Manager to determine that memory use is excessive? The Task Manager can be misleading because Windows normally allows memory usage to increase until it needs memory. A better way to determine if memory use is excessive is to use the Resource Monitor. In the performance tab of the Task Manager click on Open Resource Monitor at the bottom. In the Resource Monitor look at the Hard Faults/sec in the Memory at the bottom. If there are Hard Faults then you do have something to be concerned about.
