This post will explain 100% CPU usage. We’ve all been in that situation. When you turn on your computer, instead of going right to work, you’re met with a terrible delay and blaring fans. If you press Ctrl + Shift + Escape, you’ll notice that your CPU usage has mysteriously increased to 100%.
In Windows 10, is it possible to have 100% CPU usage? Here’s How to Get Rid of It
In this article, you can know about 100% CPU usage here are the details below;
It’s a common issue that’s usually not too difficult to resolve. There are numerous fixes to the problem of 100% CPU usage.
WMI Provider Host Using 100% CPU
WMI (Windows Management Instrumentation) Provider Host is a Windows 10 core service that connects to various software on your computer to send information about your operating system. In other words, it’s a critical process that you shouldn’t turn off carelessly. However, if you notice it using a lot of CPU in the Task Manager Processes tab, you should take action immediately.
Restarting the WMI service is the first thing you can attempt. To get started, open the Services app. (You can quickly reach there by searching for services in the Start menu.) Scroll down to Windows Management Instrumentation, right-click it, and choose Restart from the menu that appears.
If that doesn’t work, the following option is a little more involved, but it has the potential to provide longer-term remedies to your CPU problems.
If Task Manager’s WMI Provider Host process is causing your 100 percent CPU usage, you can look into the issue further. Open “eventvwr” by pressing Win + R. Go to “Applications and Service Logs -> Microsoft -> Windows -> WMI-Activity -> Operational” in the left pane. It will display all of the processes handled by the WMI Provider Host.
Look for faults in the service in the center column, “Operational,” then check the “ClientProcessId” number in the “General” tab below that. It should allow you to focus on the program or process, clogging your WMI Provider Host service.
Return to Task Manager, select the “Details” tab, then sort processes by “PID.” Locate the error-prone process, right-click it, and select “Open file location.” It will show you what software the procedure is associated with and whether you may reinstall, remove, or update its drivers, among other things.
There could be many problems like this in the WMI Provider Host, in which case you need to repeat the steps above to address each one. It’s also possible that a single app/process has been consuming your CPU all along, in which case you have to be good to go once you’ve dealt with the offender.
Disable Superfetch (or Windows Search)
Superfetch is a feature in Windows 10 that learns which apps you use the most and pre-fetches them, so they load faster the next time you use them. It’s a background process that usually doesn’t cause issues, but it doesn’t always get along with older devices.
To see if Superfetch (or another service) is consuming your CPU, open Task Manager (Ctrl + Shift + Escape), click “More details,” then “CPU” to see which processes are using the most CPU.
If you see that a “Service Host,” such as Superfetch or something else, is consuming a lot of CPU, right-click it and select “End Process.”
To permanently disable it (or until Windows turns it back on, which can happen after an OS upgrade), press Win + R, type services, and then scroll down to Superfetch in the Services box.
Right-click Superfetch, select Properties, then select “Disabled” from the drop-down next to “Startup type” in the Properties panel.
Technically, you may do this to any service hogging CPU, but some services are system-critical, so proceed with caution. Another cause of high CPU usage is “Windows Search,” which you can safely turn off as well.
Reset Your Power Plan
Changing the power choices in Windows can have a significant impact on your PC’s performance. It’s conceivable that you’re overloading your CPU if you’ve set it to “High performance” – significantly if you’ve tweaked the “plan settings.” (Older gadgets are particularly vulnerable.)
In the Start search bar, type power plan, then click “Choose a power plan.” Switch to “Balanced” if you’re on “High performance” or “Power Saver.”
To be sure, click “Change plan settings,” then “Restore default settings for this plan” on the next screen.
Check Your Power Supply
It is a problem that might affect both Windows 10 desktop and laptop users. If your power supply is defective (the mains cable on a laptop, the PSU in a desktop), it will begin undervolting your CPU to conserve electricity. When your CPU is undervolted, it can only operate at a fraction of its full power, which is why you can see 100% CPU usage on Windows 10.
On a laptop, the solution is simple:
- Disconnect your laptop from the power outlet.
- Go to Battery Options -> Power & Sleep Settings -> Additional power settings.
- Select High Performance.
If the problem was with your power supply, the CPU usage in the task manager (Ctrl + Shift + Esc) should restore to normal.
On a desktop, things are a little more tricky because you’ll have to physically remove your PC’s power supply and test another one. Before attempting this, we encourage that you read through our other suggestions provided below.
Disable Third-Party Antivirus Software
This one could be a touchy concern, but we believe that if you’re running antivirus software on Windows 10, you’re undoubtedly putting an undue burden on your CPU (mainly if it is older). Extra security isn’t always a bad thing, but you generally don’t need it.
Don’t be scared to turn off your third-party antivirus software to see whether it makes a difference in your CPU usage. If it does, uninstall it because Windows Defender should be more than enough protection.
