The problem: On a Windows 10 based computer, you may face high CPU usage problems, even without any programs running. In general, Windows 10 and without an obvious reason, can significantly slow down your PC, because, due to their new design, many services and applications can run on the background affecting your system's performance.
For that reason, in a previous tutorial I have mentioned the most common ways to optimize Windows 10 to run faster.
This tutorial contains several methods to resolve the high CPU usage issue on Windows 10.

The Window 10 high CPU usage problem, in most cases, is caused from the Windows Update background task or after a malware infection or because a specific Windows service (e.g. the "System and Compressed Memory" or the "Window Store Service", etc.) causes your system to run slow.
