Why does DWM load the processor by 30-40%?

Question

virtual box

Windows Server 2012 R2 x64 is installed on Virtual Box, I'm sitting remotely through Team Viewer 12, the problem is that the "dwm.exe" process loads the processor by 30-40%, it's rather uncomfortable to work and it causes inconvenience and consumes resources. There is not a lot of information in Google, on the off site I found a fix for a similar problem, but it is for a different version of Windows:
https://support.microsoft.com/en-us/help/2957979/d...
In the services there is nothing similar to "Desktop Window Manager" or "Desktop Window Manager" is nothing.
Has anyone experienced this or know a solution to the problem?

The system is clean, practically nothing is installed (Firefox, Team Viewer, uTorrent), only fonts are checked in "Performance", disabling all effects does not change anything.
