| 1002 | Error event indicating a critical issue that needs attention | Application Error |
| 1003 | Warning event suggesting potential problems that may arise | System Restore |
| 1004 | Information event providing details on system events | Microsoft-Windows-Kernel-Power |
Ending Resource-Heavy Processes
To end resource-heavy processes causing Windows 10/11 CPU to reach 100% usage, follow these steps:
– Press Ctrl + Shift + Esc to open Task Manager.
– Click on the “Processes” tab to see which programs are using the most CPU.
– Look for any suspicious programs or processes that are using an excessive amount of CPU time.
– Right-click on the process and select “End task” to stop it from running.
– Make sure your antivirus software is up to date and run a full system scan to check for any malware.
– Disable any unnecessary startup programs that may be running in the background and consuming CPU resources.
– Check for software updates and install them to fix any bugs that could be causing high CPU usage.
– Monitor your CPU usage in Task Manager to ensure that it stays within normal levels.
– If the issue persists, check the Event Viewer for any error messages related to high CPU usage.
Running or Disabling Antivirus Software
If your Windows 10/11 CPU usage is consistently at 100%, it could be due to your antivirus software running in the background. To check if this is the case, open the Task Manager by pressing Ctrl + Shift + Esc on your keyboard. Look for any antivirus processes that are using a high amount of CPU time.
If you suspect that your antivirus software is causing the issue, you can try temporarily disabling it to see if the CPU usage drops. To do this, locate the antivirus program in your system tray or in the Windows Start menu. Right-click on the program icon and look for an option to disable or turn off the real-time protection.
Remember to re-enable your antivirus software after testing to ensure that your computer remains protected. If disabling the antivirus software resolves the CPU usage problem, you may need to contact the software provider for further troubleshooting or consider switching to a different antivirus program.
Keep in mind that having no antivirus protection leaves your computer vulnerable to malware and other security threats, so it’s important to find a balance between computer performance and security.
Adjusting Power Plan Settings
To adjust power plan settings in Windows 10/11 to fix CPU at 100% usage issue, follow these steps:
Step 1: Press the Windows key + R to open the Run dialog box.
Step 2: Type “powercfg.cpl” and press Enter to open the Power Options window.
Step 3: Select the power plan you are currently using and click on “Change plan settings.”
Step 4: Click on “Change advanced power settings.”
Step 5: In the Power Options window, scroll down and expand the “Processor power management” section.
Step 6: Set the “Minimum processor state” and “Maximum processor state” to a lower percentage to reduce CPU usage.
Step 7: Click on “Apply” and then “OK” to save the changes.
Modifying Registry Editor Settings
To modify Registry Editor settings to fix the Windows 10/11 CPU at 100% usage issue, follow these steps:
1. Open Registry Editor by pressing the Windows key + R, typing “regedit,” and pressing Enter.
2. Navigate to “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TimeBroker” in the Registry Editor.
3. Look for the “Start” DWORD value on the right-hand side and double-click on it.
4. Change the value data from 3 to 4 and click OK.
5. Close Registry Editor and restart your computer for the changes to take effect.
By modifying these Registry Editor settings, you can potentially resolve the high CPU usage issue on your Windows 10/11 system. Remember to always be cautious when making changes in the Registry Editor, as incorrect modifications can cause system instability.
If you continue to experience high CPU usage after applying these changes, consider further troubleshooting or seeking assistance from a professional.
Turning Off Windows Notifications
To turn off Windows notifications and potentially reduce CPU usage, follow these steps:
1. Open the Start menu and type “Settings.” Click on the Settings app to open it.
2. In the Settings window, click on “System.”
3. Select “Notifications & actions” from the sidebar.
4. Scroll down to the “Notifications” section and toggle off the switch under “Get notifications from apps and other senders.”
5. Additionally, you can individually turn off notifications for specific apps by scrolling down to the “Get notifications from these senders” section and toggling off the switches for the apps you don’t want to receive notifications from.
By disabling unnecessary notifications, you can potentially free up system resources and reduce CPU usage, leading to improved computer performance and speed. This simple fix may help alleviate the issue of Windows 10/11 CPU at 100% usage.
Resetting the Computer
To reset the computer in Windows 10/11 when experiencing a CPU at 100% usage issue, you can follow these steps:

Step 3: In the Task Manager window, locate the Svchost.exe process that is consuming a high amount of CPU usage.
Step 4: Right-click on the Svchost.exe process and choose End Task from the context menu.
Step 5: Wait for the process to end and then check if your CPU usage has decreased.
F.A.Qs
Why is my CPU usage 100% Windows 10?
Your CPU usage is 100% in Windows 10 because of background running processes that may have auto-started and are running unnoticed in the background, causing a strain on your computer’s performance capacity.
Why is my CPU at 100 percent usage?
Your CPU is at 100 percent usage because your computer is trying to do more work than it can handle at that moment. This is common during computationally-intensive tasks like running games, but it may cause programs to slow down temporarily.
Why is my CPU running at 100 degrees?
Your CPU may be running at 100 degrees due to a poorly attached or malfunctioning cooler, which can lead to high temperatures. Also, incorrect application of thermal paste during installation could result in poor heat transfer.
How to diagnose high CPU usage Windows 10?
To diagnose high CPU usage in Windows 10, you can start by opening the Task Manager and sorting the processes by CPU usage to identify any programs consuming high amounts of CPU.
