6 Useful Solutions to Fix High CPU Usage in Windows 10
The central processing unit (CPU) can be regarded as the brain of the computer. All major components of the system, such as the graphics card and memory, depend on the CPU’s instructions.

When a game stalls or crashes, an open application does not respond to new input stops, or a program opens at a extreme low pace, high CPU usage may be the cause. I will introduce a list of how to fix high CPU usage in Windows 10.
Assuming the CPU usage is around 100%, it implies that your PC is attempting to perform more work than it can. Then, at that point, the speed of your PC will turn out to be slower. At the point when PCs perform computationally intensive tasks, for example, running games, they will generally use nearly 100% of the CPU.
Why does CPU usage go high? Here are 4 common reasons for this issue.
Reasons for High CPU Usage:
- Too Many Background Processes
- There Is an Annoying Antivirus or a Virus
- System Idle Process
- WMI Provider Host (WmiPrvSE.EXE)
1. Reboot
Save your document and restart your computer, this may solve the problem, especially when it has been a long time since you last restarted, restarting will clear the temporary files and probably solve the slowdown of long-running processes.
2. Update drivers
If a process is still using too much CPU, try updating your drivers. Drivers are programs that control specific devices connected to the motherboard. Updating your drivers may eliminate compatibility bugs or errors that cause increased CPU usage.
You can simply leave the task of updating drivers to the professional driver software, Driver Talent. The software will automatically update all device drivers to the latest and correct version without the need to research manually.
1. You can download and install Driver Talent on your computer.
2: Run it and click Scan. Then Driver Talent will search for your computer with the missing or corrupted drivers.
3: Click Install All to get drivers updated.
Then you will see Driver Talent update your outdated and corrupted drivers easily and quickly for your computer.
3.End the process
When you notice that the PC is getting slower than usual and the CPU 100%, you can try the Task Manager to find which processes are causing high CPU usage. Here is how to fix the 100% CPU usage issue.
Step 1: Shortcut CTRL+SHIFT+ESCAPE to open Task Manager, which can keep track of programs if a program becomes active again after a restart in terms of CPU usage.
Step 2: Click the CPU column header to sort the processes by CPU usage and check which processes cause your CPU becoming higher.
Step 3: Right-click the Process that consumes lots of your CPU and then you should click End task to finish this process.

4. Power Options
Whether you’re on a laptop or desktop, some power settings can slow down the CPU.
1. Press the Windows logo key + X keyboard shortcut, then you can access “Power Options” from the menu.

2. Click on “Show hidden plans” and then enable a non-power saving plan.

3. Now open Task Manager again and see if the CPU usage is back to normal.
5. Scan for malware
High usage may be due to malware disguised as a normal Windows process. Some malicious programs use CPU and GPU bandwidth for different purposes, such as mining, while appearing in Task Manager under familiar names such as “Cortana.exe” or “Runtime Broker” to confuse users.
Run a full scan with antivirus software to check it out.
6. Turn Windows Notification Settings Off
Windows notification settings on Windows 10 PCs may trigger CPU 100%. You may follow the steps below to modify the Windows notification settings to fix the issue:
Step 1: You should click the Start button and click Settings to open the Windows Setting.
Step 2: Then choose System and click Notifications & actions on the left side of the pane.
Step 3: At last, you just need to turn off the feature Get notifications from apps and other senders.
