Many people must have had too much CPU occupation. At this time, the computer will generally respond to abnormal jamming. What should we do in case of such a thing? Now I'll take you to understand it!
Generally speaking, high CPU consumption is caused by running some applications in the background or the system is executing some commands.
Task Manager
Background applications are divided into several situations, rogue software, automatic game update, or other your own operations. At this time, you can directly open the task manager to see which process takes up a lot. If the software you started takes up a lot, there's no way but to wait.
If it is rogue software, you need to use killing software such as 360 or Tencent security housekeeper to help clean up and prevent its recovery. Many rogue software are particularly powerful, and it is difficult for ordinary users to clean it up. If you can't solve it, reinstall a clean system.
The operations performed by the system itself mainly include automatic system update, disk defragmentation, Windows Defender scanning files, etc. These are the common ones.
System update can be solved by turning off relevant services. For specific process, right click this computer - Management - services and applications - Services - Windows Update - properties - Startup type: disabled.
Windows Update
You can right-click Disk C - properties - tools - optimize the drive and defragment - optimize to enter the interface and set the time of automatic optimization defragmentation.
Disk optimization
Just close windows defender directly. The process is set - update and security - Windows Defender - close, and then it's OK.
These are the common cases of excessive CPU occupation. If your processor is a very old product and the occupation is still high after the above conditions are eliminated, it indicates that the performance may not keep up with the requirements of the system. It is recommended to install an old version system such as WinXP or win7; Or directly replace the new platform.
