CPUs are not running at its full capacity in Windows 10

Suddenly I found my CPUs are not running at its full capacity (max 30%).

I found solution Disable Intelppm registry in Registry Editor:

1. Edit the registry (HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\intelppm\Start = 4
2. Or Execute "sc config intelppm start= disabled"
3. Reboot your computer.

I found this solution in the following article:
