On my Windows 10 Home, I was being bugged by constant freezes which forced me to hard reboot now and then. Since I use Ubuntu as my primary OS, I chose to adjust with this for long. However, this became more of a trouble in the recent times with Windows starting up at 98% CPU usage and every process actually showing 0% CPU usage. That's when I decided to get into the root of the problem and resolve it. I was confident that the hardware was fine since Ubuntu worked perfectly all the time.
It turned out that many Windows 10 users, especially those who upgraded from previous versions of Windows 7 or 8 / 8.1 faced similar freezing issues. The answers at Windows Forums by Microsoft staffers generally suggested using the command sfc /scannow to verify that system files were intact. However, most users found it unhelpful and that didn't help me either.
