The computer is dying. This is what we often hear. It takes half a day to open a program. Why does the new system slow down? This is a common problem. In fact, most of the time, instead of slowing down the computer, CPU just ran to do useless work. If you don't believe it, when you feel the computer is very slow, press the "Ctrl+Shift+Esc" button to turn out the "task manager" to see if the value of "CPU use" column in the status bar is close to 100%. If this is the case, and we ourselves do not carry out any operation that requires a lot of computation, the 80% is CPU running to do useless work.
What kind of useless work is CPU doing? How should we solve this problem? At this time, most people choose to reinstall the system. Although the reinstall system is not very troublesome, it also takes a lot of time. If we can solve these problems, why do we need to reinstall the system? Next, please come with me to find out the source and not let CPU do useless work.

First, the death of a machine is a curse of laziness.
After the boot, the computer is basically in a state of no response. The desktop does not show for half a day. The icon in the system tray is channeling out one by one, opening the task manager. The "CPU usage" shows 100%. The main reason for this problem is that too many self priming items are loaded on the boot system, which results in overload operation of CPU.

After the computer can be used normally, click "start" and "run" in turn, enter "msconfig" in the open "run" dialog box, and click "confirm" button to turn on "system configuration utility". In the open dialog box, click the "start" tab to remove the selection in front of the program which does not need to start, and finally click the "confirm" button.

In addition to the programs loaded by "startup" items, some programs will register themselves as system services in order to enhance their "robustness". You can also cancel the unwanted service, or switch to the service label in the system configuration utility. In order to prevent any system service from disabling the system, you can check all the hidden Microsoft services options and then judge the name of the service according to the name of the service.

In addition, storing too many things on the desktop will also affect the loading speed of the desktop. Many people have this habit. All the program icons are placed on the desktop, so it is convenient to use. Friends sent from QQ files, regardless of size, are all placed on the desktop for a long time. When the number of icons on the desktop is too large and the storage files are too large, it will affect the loading speed of the desktop, thus slowing down the whole system and causing the system to die.
