Windows 10: Why does task manager report my GPU usage when I don't have a GPU?

It's being used for 'Desktop Window Manager', Chrome and Norton Security, and it says I'm using 'GPU 0 - 3D' and 'GPU 0 - Copy'. Any reason why? I'm only curious.

Desktop Windows Manager high GPU usage persists

Several individuals have reported Desktop Window Manager (dwm.exe) using unrealistic amounts of GPU for video playback, gaming, or any high graphics intensive activity. Here is a list of just a few of the many requests for support on this issue:

Example 1

Example 2

Example 3

Example 4

Example 5

It has been a few years now that this problem has been reported, are there any accepted fixes. From what I gather, even those individuals with serious graphics cards are vulnerable to dwm.exe dominating their available GPU. I myself report this issue, even
on games and design software with the settings at a minimum. For example, Java will be using ~45% of the available GPU, whereas dwm.exe takes up the remaining ~55%. As stated previously, the result is the entire system halting, not just the game. The mouse
will take a few seconds to stutter across the screen, and task manager will take 5+ seconds to even appear.

There have been many suggestions and no results. Is that Microsoft's consensus then? Thank you ahead of time.

 

Task Manager GPU readout not correct.

Hello! I've got a 2-GPU system that I'm using to run Folding@Home. This, naturally, fully loads both graphics cards. However, Windows Task Manager only shows a 0-2% load on the cards. This also occurred when running a video game for a more normal GPU task.
Radeon Settings, GPU-Z, and MSI Afterburner all correctly showed usage at 99%, as well as my video card's light-up 'Tachometer'. Why is task manager failing to detect this load?

 

GPU graph is not seen in task manager

Hi Sree,

You can now view GPU performance in the Task Manager in Windows 10 if you have a dedicated GPU, the Task Manager will show you performance stats for both the integrated and dedicated GPU since you just mentioned that you've already upgraded your PC to the Fall
Creators Update. But, since the GPU graph is not showing on your PC's Task Manager, there's a possibility that your computer wasn't meet requirements for GPU in the Task Manager. To know more about it, you may check this article:
