What do the number of processes and CPU percentage mean in Task Manager? Please introduce the hero

It's how much the CPU is using to analyze the data!

CPU Usage: indicates the percentage of CPU resources that are currently used. If your CPU usage is too high for a long time, that's an indication of:

1 is that your computer is poisoned.

2. There is a software error.

3. It's time to upgrade your computer.

CPU Usage History: A graph showing the change of CPU usage over time, the default refresh rate is once every two seconds, you can adjust the refresh rate through the view menu, if your CPU is dual-core, or hyper-threaded, the usage of both cores will be displayed here Showing the usage history of both cores.

PF usage: PAGEFILE (virtual memory), when the physical memory is not enough, put the data that is temporarily not used into the virtual memory file of the hard disk, and then call it out when it is used, the best way to reduce the PF usage is to increase the memory.

The use of PF is too high, which indicates:

1 is that your physical memory is too small.

2. The program you started is too large (e.g. ps) too much.

3. Your virtual memory settings are unreasonable, and often pop up if the virtual memory is insufficient, you can change it through My Computer Properties Advanced Performance Settings Advanced Virtual Memory Settings Select the partition where the virtual memory is placed (it is recommended to put it in the partition outside the system disk) Select a custom or system-managed size Settings OK.

Set Virtual Memory Page File Usage History: A graph that shows how virtual memory usage has changed over time, and you can adjust the refresh rate through the View menu.

Handle: A value used to uniquely identify a resource, such as files and registry keys, so that programs can access it. It is a pointer of a pointer.

Thread: An object in a process that runs program instructions, threads that allow concurrent operations in a process and enable a process to run different parts of its program at the same time on different processors.

Process: An executable program or a service.

Physical memory: Your computer's physical memory usage.

Total: The total amount of physical memory.

Available Memory: the remaining available amount of physical memory, which refers to the remaining physical memory before virtual memory is used.

System Cache: The amount of physical memory allocated for system caching. It is mainly used to store some key programs and data. As soon as the system or program needs it, some of the memory will be freed up.

Total: refers to the sum of the physical and virtual memory currently in use.

Limit: The maximum sum of physical and virtual memory that the system can provide.

Peak: refers to the highest memory usage record from the current boot to the present.

Core memory: The amount of memory used by the operating system and necessary drivers.

Total: The total amount of physical memory used by the operating system and necessary drivers.

Number of pages: The memory that can be copied to the page file, and it will be used if the system needs it"Mapping"to the hard disk, which frees up some of the physical memory.

Unpaged: Memory that remains in physical memory, which is not mapped to the hard disk, i.e., the page file.

Here's how to recover:

1. The current status is as shown below, only the tasks are displayed:

2. Double-click on the blank space at the edge of the dialog box

3. You can return to normal display, as shown below

Double-clicking the left mouse button in the left and right sidebars of Task Manager shows it because you inadvertently double-clicked the left mouse button and the menu bar is hidden.

Definitely. The main thing is that the number of processes is a bit too much. If you need to identify it, take a screenshot of it

The path is not right-clicked on the program you need to query, enter [Open Directory] can also be like this, the default is not to display the path, you can click [View] in the menu bar of the Task Manager - Select Columns], check the [Image Path], and then maximize the task.

You can pull it to the left, you try.

In the taskbar dialog, :View:Find!

This usually doesn't happen!
