How To Fix 100% CPU Usage In Windows

Computers generally consume a small amount of CPU. They use only 5% of their CPU power. Whenever users play video games, run applications, the CPU usage rises temporarily.  Once the processes running are closed, the CPU usage falls. Consider that no application requires more than 50% of CPU.

Although the programs can cause high CPU usage without your knowledge, this happens when a program faces an unexpected error. If the programs running are using CPU at 100%, it will have to free up processing power for different processes, which will make your computer slow.
