vmmem is using a lot of RAM with Win10

vmmem, supposedly something to do with virtual machines, uses 1.5 GB of RAM even though no VM is active in Hyper-V. I do run docker though. The vmmem is also run as a user with a username which looks something like E076D8C-04EC-...

Is this expected behavior or is there some way I can troubleshoot it?

Edit: I shut down the Docker Desktop and then the vmmem is not there anymore.

Docker is a type of virtual machine, and if it is running, it will use memory like any virtual machine in any virtualizer.

"Proof" You shut down Docker (the machine) and the memory is released. This, too, is completely normal.

All is well.
