Win 10 'Treshold 2' very high cpu usage by 'System and compressed memory' process

I did a clean install of Windows 10 Treshold 2 (aka version 1511) on my 2015 15" MBP and I ran into a problem. Well two actually:

1. The Realtek driver installation hangs when installing the BC support software. This is easily fixed by killing the RealtekSetup.exe process.

2. The process "System and Compressed Memory" now continuously uses one of the eight cores which ruins battery life. I had to actually change the power plan in Windows to allow the CPU to only go to 60% maximum frequency.

From some googling I gathered many are suffering from this problem on other brands and it's usually related to a bad driver. I haven't been able to find the culprit yet unfortunately.

Now here's my question: is anyone suffering from this issue as well and if so where you able to solve it?

Thanks!
