The problem of high CPU usage can be solved by the following methods. First, open the task manager, sort the CPU occupancy and find the process with high occupancy and process it; secondly, disable unnecessary startup items in the boot tab, and close the background application permissions; then update the driver and system through the device manager or manufacturer tools; finally use the disk cleaning tool to clear temporary files to improve system efficiency.
High CPU usage is a common problem on Windows 10, especially when you run multiple programs or have hidden processes in the background "stolen" resources. The key to solving this problem is to find out which process is consuming a large amount of CPU and then deal with it according to the situation. Here are some practical methods to help you quickly locate and alleviate the high CPU usage problem.

Check out the task manager to find out the culprit
The first step is to open the task manager (Ctrl Shift Esc), switch to the "Process" tab, and click on the "CPU" column to sort. This allows you to see which programs or system processes are consuming a lot of CPU resources.

Common situations include:
- Too many tabs on the browser (especially Chrome)
- Backend tasks such as system update, antivirus software scanning, etc.
- Certain malware or ad plugins
If you find that an unknown process occupies a high CPU, you can right-click to select "Search Online" to check the function of the process, or directly end it to see if it has any impact.

Close unnecessary startup items and background applications
Many programs will start by default by booting, which not only slows down the startup speed, but may also quietly occupy CPU resources. Similarly, in the Startup tab of Task Manager, you can disable some uncommon boot items.
Also, in "Settings > System > Notifications and Actions", turn off those background application permissions that you do not need. For example, some weather and news apps may refresh data in the background even if they are not opened, causing additional burden.
Update drivers and systems to fix potential bugs
Sometimes high CPU usage is caused by outdated drivers or system bugs. Especially for key drivers such as graphics card drivers and motherboard chipsets, it is recommended to check and update regularly.
You can manually update the driver through the "Device Manager", or you can use the driver detection tool provided by the manufacturer's official website. While keeping the Windows system as the latest version, Microsoft often fixes performance-related issues in updates.
Clean up system garbage and temporary files
Long-term Windows runs will generate a large number of temporary files and caches. Although these will not directly lead to high CPU usage, they will affect the overall system efficiency and indirectly increase the CPU burden.
You can clean up regularly with the built-in "disk cleaning" tool, or with third-party software such as CCleaner. If you find that the system is slowing down and the CPU continues to run at a high level, you might as well try this method.
Basically these are the more practical operations. The key is to check the source of the problem first, and then deal with it in a targeted manner. Sometimes restarting the computer can temporarily alleviate the problem, but if there are frequent high CPU usage, you need to check in depth whether there is any problem at the hardware or software level.

Vmmem or virtual memory can cause high CPU or memory usage due to various factors. One of the key reasons behind this issue is some resource-intensive processes running in the virtual host. However, if this is not the case and the VM still consumes a lot of system resources in idle mode, it may be a driver failure. This slows down the virtual machine and your work may stop. So, follow the steps below to resolve the issue quickly. Fix 1 – End all resource-intensive processes If you are running some heavy applications or software versions, expect vmmem to use a lot of resources. There is nothing unusual about this. Even if you can kill these processes directly, it will free up more resources for your device. NOTE – You can

Windows 11 has a built-in widget platform that may cause high CPU usage. These widgets can be used to display weather forecasts, sports scores and clocks. While they may be useful to some extent, some users complain that Windows 11 widgets use too much CPU. This widget issue is most common on Windows 11 devices, but older versions of Windows may also experience this issue. Widgets are a useful feature that provide you with information at a glance. However, sometimes, when a widget panel is open, it starts consuming CPU or memory and system performance degrades. The CPU is the brain of the computer. It executes the operation of your machine

The sudden high and low CPU usage is caused by a program error. The solution is: 1. Use reliable anti-virus software to completely clean the system memory and local hard disk; 2.

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 other programs.

What to do if the CPU usage is 100? Why? In recent years, with the rapid development of science and technology, computer technology has become an important part of modern society. Whether for personal use or corporate work, computers play an important role. However, when using the computer, we sometimes encounter situations where the CPU usage soars to 100%, which brings great trouble to our work and study. So, what is the reason for 100% CPU usage? How should we deal with it? First, let's take a look at what causes

What to do if the CPU usage is 100 When we use the computer, sometimes we will encounter a situation where the CPU usage reaches 100%. CPU usage refers to the load level of the computer's processor performing tasks. When the CPU usage reaches 100%, it means that the CPU reaches the limit of its processing power when performing tasks, which may cause the computer to run slower, or even freeze and crash. Here are some ways to deal with and resolve 100% CPU usage. End the process occupying the CPU: First, we can use task management
