Solution to cpu usage 100: 1. Restart; 2. Update driver; 3. End or restart the process; 4. Scan for malware; 5. Check power options; 6. Reinstall Windows; 7. Use another program.
#The central processing unit (CPU) can be said to be the brain of the computer.
All major components of the system, such as the graphics card and memory, rely on instructions from the CPU.
When the game freezes or crashes, open applications become unresponsive, or programs open slowly, the CPU usage may be abnormally high.

Especially if a long time has passed since your last reboot, rebooting can clear out temporary files and potentially resolve slowdowns in long-running processes.
Method 2. Update the driver
If there is only one process and it is still using too much CPU, try updating your driver, which may eliminate compatibility issues or errors that cause increased CPU usage. .
If you don’t want to bother studying how to update drivers, the easiest way is to use professional driver software to automatically update the drivers of all your devices to the latest and correct versions, saving time and effort.

Some bugs can also be fixed by updating the BIOS version.
The BIOS (Basic Input Output System) is the firmware installed on the motherboard that issues instructions to other components of the computer at startup.
But updating BIOS usually does not lead to performance improvements, and may even bring new problems, so only after you identify the error causing high CPU usage and find a BIOS update that directly solves the problem It is only recommended to do this.
Method 3. End or restart the process
1. Right-click the taskbar at the bottom of the screen, click and select [Task Manager], if a program starts to use active CPU again after restarting , Task Manager can track these programs.

Some malicious programs occupy CPU and GPU bandwidth for different purposes, such as mining, while running as "Cortana. exe "or"Runtime Broker "Wait for familiar names to appear in the task manager to confuse people.
You need to use anti-virus software to conduct a comprehensive scan and check.
Method 5. Power options

Method 7. Use other programs
CPU-Z is a reliable tool for checking general information about your CPU and motherboard.
After installing and opening it, you'll see the exact models of your CPU and motherboard, as well as some performance information. Use these models to search the web for support threads related to CPU usage.
Task Manager is not the only way to view background processes. Process Monitor records not only CPU usage, but also registry, file system, and network activity. If you suspect a process may be malware, use this tool to check network activity.
Similarly, Performance Monitor is a native Windows tool that allows you to understand the CPU usage time of a process in detail. Shortcut Windows key R, enter "perfmon".
Performance Monitor lets you break each process's CPU usage into multiple categories and track it over time for advanced troubleshooting.
