In the event of a program jam or the like, everyone generally opens the task manager to close the process, and the "Properties" tab in the task manager can also provide information about how the computer uses system resources (such as random access memory ( Advanced details for RAM) and central processing unit (CPU). The following system home Xiaobian will introduce you how to open the Win8 system task manager.
1. Open the “Task Manager' by right-clicking on the taskbar and clicking on &# Task Manager”.
2. Or use the combination hotkey Ctrl + Alt + Del, and then in the pop-up interface, select Task Manager;
3. Click the “ Application” tab to see To the application that is running on your current system, if you have some programs that cannot be closed or unresponsive through this program interface, you can disable it in the Applications tab.
4. Click the <quo;process” tab and you will see the real name of the application you are running on your current system. If you are experiencing high CPU usage or slow system, you can Find a program that uses a lot of memory in this tab. If you can confirm that this program is not currently needed, you can manually deactivate it.
5. Click the <quo;process” tab and you can see the CPU and memory usage. Let's take a look at the parameters and functions of the performance manager.
Function 1: Monitoring The number of CPU and memory resources
<;performance" tab includes four charts.
1. The red box area shows the number of CPUs used at the moment and in the past few minutes. (If the "CPU usage record" is displayed separately, the computer has multiple CPUs, or a dual-core CPU, or both). A higher percentage means that the program or process requires a lot of CPU resources, which slows down the computer. If the percentage freezes around 100%, the program may not respond.
2. The two graphs in the blue box area show the current time and the amount of RAM or physical memory used in the last few minutes, in megabytes (MB). The "Task Manager" window lists the percentage of memory being used at the bottom of the window. If memory usage seems to remain high or significantly degrades your computer's performance, try reducing the number of programs that are open at the same time, or installing more RAM.
3. To view the memory usage of a separate process on your computer, click the “process” tab. By default, the "memory (private working set)& rdquo; column is selected. A private working set is a subset of a working set that is a technical term describing the amount of memory used by each process. A private working set specifically describes the amount of memory that a process is using and cannot share with other processes.
4. If you are a more demanding user, you may want to see other advanced memory values on the “process” tab. To do this, click “View”, "Select Columns", and select a memory value:
- Memory - Working Set. The amount of memory in the private work set is in use and the process is in use The sum of the amount of memory shared by other processes.
- Memory - Peak Working Set. The maximum number of working set memory used by the process.
- Memory - Working Set Increment. The amount of change in the working set memory used by the process.
- Memory - Approved Usage. The amount of virtual memory that the process reserves for the user.
- Memory - Paged Pool. The amount of approved virtual memory for a process that can be written to other storage media, such as a hard disk.
- Memory - Nonpaged Pool. The amount of approved virtual memory for a process that cannot write to other storage media.
Feature 2: Get detailed information about the amount of memory being used
The three advanced tables in the green box area list various details about memory and resource usage.
1.“Physical Memory (MB)> The total number of RAMs on the computer is listed in megabytes (MB). "Cache" refers to the amount of physical memory recently used for system resources. “Available Quantity" indicates the amount of memory that is not currently used or contains no useful information (unlike a cache file containing useful information).
2. The total amount of memory in the core memory (MB)” indicates the amount of memory being used by the core part of Windows (called the kernel). "Pages" refers to the amount of virtual memory the kernel is using. “Unpaged” indicates the amount of RAM memory used by the kernel. The
“system” table contains the following five fields:
- The number of handles. The number of unique object identifiers that the process is using. IT professionals and programmers usually pay attention to this value.
- Number of threads. The number of objects or processes running within a larger process or program. IT professionals and programmers usually pay attention to this value.
- Number of processes. The number of individual processes running on the computer (this information can also be viewed on the “process” tab).
- Boot time. The amount of time that elapses after a restart operation is performed on the computer.
- Page file. A description of the use of virtual memory (also known as paging files). The page file is the space on the hard disk that Windows uses instead of RAM (in case of insufficient RAM). The first number is the amount of RAM and virtual memory currently in use, and the second number is the amount of RAM and virtual memory available on the computer.
3. To view advanced information about the memory and CPU resources being used, click the <quo;Resource Monitor” button. “Resource Monitor Shows the same graphic summary as in Task Manager, but in more detail. "Resource Monitor> also contains detailed information about resources such as disk usage and network usage.
