Parallels 12 + Windows 10 = High CPU usage

[PaulS16]

After upgrading to Parallels 12, my Windows 10 VM is using around 110-220% CPU in macOS (Activity Monitor). It's roasting my CPU to 212-219F. Even with coolers running at 5940/5500RPM.
I'm running macOS Sierra 10.12.1 (16B2555) and Parallels 12.0.2 (41353) on a top end Retina Macbook Pro from 2013 (2.7GHz i7, 16GB DDR3, 500GB SSD, GF GT650M).

I have tried to reinstall Parallels Tools as described here: http://kb.parallels.com/en/123268
Tried to create a new VM and use the same image: http://kb.parallels.com/eu/116263
Adding boot flag to disable usb mouse: https://forum.parallels.com/threads...erformance-windows-10-au-parallels-12.338065/

Uinstalling Parallels Tools lowers the VM's CPU usage to 4-30%!
Obviously there's a problem with Parallels Tools for Parallels 12.

Thoughts, ideas?

Can you give the emulator to use more than only one core and more ram? I have the impression that this is intentional so that you have to use Windows 11 Arm.
I went from Windows to avoid using Windows 11 and now I'm forced to this crap of OS as a VM. I thought, that I'm away from it. Please do something. Thats the only issue I have with Parallels.
I use a MacBook Pro M2 Max with 38 Core GPU, 64GB RAM and 2TB SSD and I'm waiting for the Mac Studio M4 Ultra with 256GB RAM (hopefully 512GB RAM) and 8TB SSD.
