Cause of 100% CPU error

100% CPU error often causes stuttering and lag on devices such as laptops and PCs running Windows 10 and 11. This error often comes from:

• - Programs running in the background are very heavy.

• - System conflict error between Windows Services.

• - Caused by a virus.

The consequences of a 100% CPU error will make you unable to interact with the software, possibly getting a Not Responding error and even freezing. At this point you will have to hot shutdown the device (hold down the power button for about 5 seconds). If this situation occurs for a long time, the device's lifespan will be significantly reduced. So how to fix 100% CPU error?

After restarting, you can let the device rest for 5 to 10 minutes to let the internal components rest for a while, then press the power button to turn it back on.
