Quick solution is to unplug the power, to finish all instalation.
Safe mode works without interruption.

This didn't help at all:
Power options - HP Optimized selected, or if choose Power saver - it goes back to CPU 100% usage.
Options - Processor power management - lower than 100%, CPU usage still high.
Screen birightness - Windows mobility - Display Brighness - to 50%.
