Windows command--taskmgr 1

Taskmgr.exe is used for Task Manager. It displays the processes that are running in the system.

The program uses Ctrl+alt+del (typically pop-up Windows security and then click on "Task Manager") or Ctrl+shift+esc

Sometimes need, QQ remote client computer, and then in which to perform mstsc, and if MSTSC open the desktop of the terminal is not displayed, need to open its Task manager, usually press Ctrl+alt+end, (Ctrl+alt+del will open the local task Manager, Cannot open remote Task Manager), but this time often also failed,--seemingly ctrl+alt+end this shortcut is occupied by QQ,--but TeamViewer will not be so, but TeamViewer is charged, is often suspected of commercial use, inexplicably disconnected ... Depressed

Today finally found the Ctrl+alt+del, also can.

㈠, overview, and Menu Task Manager provides information about the programs and processes that are running on your calculations. Also displays the most common units for measuring process performance. Use Task Manager to monitor key indicators of computer performance. You can view the status of a running program and terminate a program that has stopped responding.　　You can also use up to 15 parameters to evaluate the activity of a running process to see graphs and data that reflect CPU and memory usage.　　In addition, if you are connected to the network, you can view the network status to see how the network is functioning. If there are multiple users connected to your computer, you can see who is connected, what they are doing, and can send messages to them. 1, change the display options in Task Manager, and click the tab that corresponds to the display option that you want to change. Click: The Applications tab to view details, large icons, or small icons. Processes tab, you can select the columns to display. The Performance tab, you can change the CPU usage record graph and display the kernel time. Network tab to view information about your network connection. On the View menu, click the command you want. Note To display the kernel time to add a red line in the CPU usage and CPU Usage records graphs, click the Performance tab. On the View menu, click Show Kernel time. The red line indicates the amount of CPU resources consumed by the kernel operation. 2, update the Task Manager data on the View menu, click Refresh Now. Note To change the frequency of automatic data updates, on the View menu, point to Update Speed, and then click the command that you want. To temporarily pin the data that is displayed in Task Manager, on the View menu, point to Update Speed, and then click Pause. By default, data is automatically updated every two seconds. The ㈡, Applications tab displays the status of the programs that are running on the computer. In this tab, you can end, switch, or start a program. 1, start a new program, click New Task in the Applications tab. In the Open box, type or select the name of the program that you want to add, and then click OK. Note the new task corresponds to the Run command in the Start menu. If you do not know the name of the program you want to add, click Browse to search for the program. 2, switch to another program on the Applications tab, click the program that you want to switch to, and then click Switch to. 3, change the priority of a running program on the Processes tab, right-click the program that you want to change, point to set Priority, and then click the command that you want. Note To view the priority of a program that is running, on the Processes tab, click Select Columns on the View menu. In the Select Columns dialog box, select Basic priority, and then click OK. Changing the priority of a process can make it run faster or slower (depending on whether it is an elevation or a lower priority), but it can also have an adverse effect on the performance of other processes. 4, use Task Manager to terminate the program on the Applications tab, click the program that you want to terminate, and then click End Task. Note any unsaved input data or changes made in the program will be lost. If you cannot end the program immediately by using End Task, you can click the program that you want to terminate, and then click Go to process to do so on the Processes tab. The ㈢, Processes tab displays information about the processes that are running on the computer. For example, you can display information about CPU and memory usage, page faults, handle counts, and many other parameters. 1, the Process counter column header on the Processes tab, you can use the following counters to monitor running processes that can be displayed as column headings. To display a process as a column heading, on the View menu, click Select Columns. Select the check box that corresponds to the process that you want to display as a column header. The base priority determines the priority of the processor in the order in which the process threads are processed.　　You can use Task Manager to view and change the base priority. For Message Queuing, the attribute that specifies the priority of the queue in the public queue. You can set the base priority to- +,768To 32,767; The default priority is 0. The private queue does not support the base priority. Message Queuing first routes and delivers messages based on the base priority, and then routes and delivers messages based on the message priority level. CPU time in Task Manager, the total processor time, in seconds, that the process used from startup. CPU usage in Task Manager, the percentage of time that the process has used the CPU since the last update. In Task Manager, on the Processes tab, the column header is CPU. GDI objects are objects from the Graphics Device Interface (GDI) library of the Application Programming Interface (API) for graphics output devices. In Task Manager, the number of GDI objects currently used by the process. Number of handles in Task manager, the object handle in the Process object table. (Handle: In the user interface, an interface that is added to an object for easy manipulation, resizing, shaping, or other functions that belong to an object.) In programming, a pointer-to-pointer, which is a token that allows a program to access the identified resource. The image name is the name of the process in Task Manager, which is the image names. I/O Other non-read non-writable input generated by the process in the Task Manager/output operations, which include file, network, and device I/O. An example of this type of operation is a control function. "Other types of i/that point to the console (console input object) handleO "is not counted. I/O Other bytes in Task Manager, non-read non-write input generated by the process/outputs the number of bytes transferred in the operation, which includes file, network, and device I/O. An example of this type of operation is a control function. "Other types of i/that are directed to the console (console input object) handleo bytes "is not counted. I/O read input generated by the process in the Task Manager/output operations, which include file, network, and device I/O. An example of this type of operation is a control function. "i/" that is directed to the console (console input object) handleO read operation "is not counted. I/O Read bytes in the Task Manager, the input generated by the process/outputs the number of bytes read in the operation, which includes file, network, and device I/O. An example of this type of operation is a control function. "i/" that is directed to the console (console input object) handleO Read bytes "is not counted. I/O Write input to write in Task Manager, generated by the process/output operations, which include file, network, and device I/O. An example of this type of operation is a control function. "i/" that is directed to the console (console input object) handleThe O write operation is not counted. I/O The writing section in Task Manager, the input generated by the process/outputs the number of bytes written in the operation, which includes file, network, and device I/O. An example of this type of operation is a control function. "i/" that is directed to the console (console input object) handleO Write bytes "is not counted. Memory usage in Task Manager, the current working set of the process, in kilobytes. The current working set is the number of pages currently residing in memory. In the Task Manager Processes tab, the column headings are memory usage. Memory usage Delta in Task Manager, the amount of memory that has been used since the last update, in kilobytes. Nonpaged Pools never page into the disk's operating system memory. Page scheduling is the use of infrequently used programs to move parts of the working memory from RAM to other storage media, usually hard disks. In Task Manager, the amount of memory that the process uses in kilobytes.　　Page fault occurs when the software tries to read or write to a virtual memory location that is marked as "not present." In Task Manager, a page fault is the number of times a process must be retrieved from disk when the data is not in memory. The page fault value accumulates from the time the process started. Page error increment in Task Manager, the number of page faults that have been changed since the last update. The virtual memory that the paged pool has assigned to the process, which is already allocated to the paging system. Page scheduling is the use of infrequently used programs to move parts of the working memory from RAM to other storage media, usually hard disks. In Task Manager, the amount of system allocation virtual memory that the process uses is in kilobytes. Peak memory usage in Task Manager, the peak of physical memory that resides in the process since the process started. The PID (process identifier) uniquely distinguishes the numeric identifier of the process at run time. Use Task Manager to view the PID. The session ID owns the Terminal Services session ID for the process. Counters can be used only if the Terminal Services counters are installed. Thread count in Task Manager, the number of threads that are running in the process. The user name enables Windows to identify a unique name for the user account. The user name of the account must be unique among the other group names and user names in the domain or workgroup in which it resides. (User: A special group that contains all users with user rights on the server. When a Macintosh user assigns permissions to everyone, those permissions are also assigned to the users and guests of the group. The USER Object window Manager object, including Windows, menus, cursors, icons, exception branches, accelerators, monitors, keyboard layouts, and other internal objects. In Task Manager, the number of user objects currently used by the process.　　Virtual memory size in Task Manager, the number of virtual memory or address space assigned to the process. (Virtual Memory: A temporary memory used by a computer to run a program that requires more memory than the computer has.)  For example, a program can access 4GB bytes of virtual memory on a computer's hard drive, even if the computer has only +MB of RAM. Program data that is not currently loaded into the computer's memory is saved to the paging file. (Paging file: A hidden file on a hard disk that Windows uses to store parts of programs and data files that cannot be loaded into memory.) The paging file and physical memory or RAM constitute virtual memory. When needed, Windows moves data from the paging file to memory and then moves the data from memory to the paging file to make room for new data. The paging file is also known as a swap file. )2, specify the Process counter column header on the Process tab, on the View menu, click Select Column. Select the check box for the process counter that you want to display as a column header, and then click OK. Note For more information about the process counters, click Related Topics. 3, sort the list of processes on the Processes tab, click the column heading that you want to sort by. Note To reverse the sort order, click the column heading again. 4, use Task Manager to terminate the process on the Processes tab, click the process that you want to end, and then click End Process. Important be careful when terminating a process. If you end the application, you will lose unsaved data. If you end the system service, some parts of the system may not work correctly. Note to end a process and all processes created directly or indirectly by it, right-click the process that you want to end on the Processes tab, and then click End Process Tree. If you terminate the process tree of an e-mail program, such as Microsoft Outlook, it also terminates the associated process, such as the MAPI spooler Mapisp32.exe. 5, assigning a process to the processor on the Processes tab, right-click the program you want to assign, click Set Affinity, and then click one or more processors. Note the set affinity command is available only on multiprocessor computers. Use the Set affinity command to limit the execution of a program or process to a selected processor, and may result in overall performance degradation. The ㈣, Performance tab shows a dynamic overview of computer performance, including graphs of CPU and memory usage. The total number of handles, threads, and processes that are running on the computer. The total number of physical, core, and approved memory (KB). Description: View computer Performance Click the Performance tab. Note The Performance tab displays information about the performance of the computer, such as CPU and various memory usage. For more information about the fields that are displayed on the Performance tab, click Related Topics. 1, CPU Usage indicates the percentage of processor working time in the chart. This counter is the primary indicator of processor activity. View the chart to see how much processing time you are currently using. If your computer appears to be running slowly, the chart displays a higher percentage. 2, the CPU uses records to show graphs of how much CPU usage changes over time. The sampling situation shown in the chart depends on the update speed value that you selected on the View menu. Several possible values for the update are: High= two times per second; normal = once every two seconds; low = once every four seconds; pause =The monitor does not update automatically. 3The amount of paging files that the PF usage is being used by the system. If your computer is running close to the maximum, you can increase the size of the paging file. 4, the paging file uses a chart that shows the amount of paging file changes over time. The sampling situation shown in the chart depends on the update speed value that you selected on the View menu. 5, the total number of handles , threads, and processes that are running on the computer. 6, execution memory (K) is allocated to programs and operating system memory. Because the memory that is copied to the paging file (known as virtual memory) exists, the values listed under peak can exceed the maximum physical memory. The value of total is the same as the value shown in the page file Usage records chart. 7, physical memory (K) The total physical memory installed on the computer, also known as RAM. "Available" indicates the amount of memory available for use. The system cache displays the physical memory of the page that is currently used to map open files. 8, kernel memory (K) the memory used by the operating system kernel and device drivers. Paging is memory that can be copied to a paging file, freeing up physical memory. The physical memory can then be used by the operating system. Non-paged is the memory that is kept in physical memory and is not copied to the paging file. The ㈤, Network tab displays a graphical representation of network performance. It provides a simple, qualitative indicator to show the status of the network that is running on your computer.　　The Network tab is displayed only if the NIC is present. On this tab, you can view the quality and availability of your network connection, whether it is connected to one or more networks. Description: View network Connections click the Network tab. Note The Network tab is displayed only if the NIC is present. The Network tab indicates the network traffic for the connection that is connected to the local computer.　　For more information, click Related Topics. The Network tab provides instructions for how much network traffic the local computer is connected to. By referencing it, you can quickly determine the amount of network bandwidth that is being consumed.　　With multiple network connections, it is easy to compare the traffic per connection through the tabs.　　If you have more than one network card on your computer, the chart displays a composite index that contains all the networks to indicate all network traffic. To display visible lines in the network traffic graph for all interfaces, the view is automatically scaled to magnify the relationship view between traffic and the visible bandwidth. Thus, in the case of low traffic, the full height of the chart can represent only 5 of the available bandwidth%。 When traffic is higher than this level, the zoom level is reduced to show the current traffic view at a lower magnification (for example, 10% of the total available bandwidth is displayed)). The greater the percentage shown on the chart, the smaller the magnification of the traffic (relative to the available bandwidth). The zoom factor is displayed on the chart.　　To disable the zoom feature, on the Options menu, click Autoscale to toggle the value of the zoom factor. In addition, you can change the column headings that appear below the chart. These headings are described in the following table. The NIC name is the name of the network adapter in the Network Connections folder. The adapter describes the description of the adapter, typically the same as the device name in the Network Connections folder. The network leverages the percentage of network utilization, based on the initial connection speed of the interface. Link speed is the interface connection speed that originates from the initial connection speed. The percentage of connection bandwidth used by the sending byte throughput from the computer during the polling time period. The percentage of connection bandwidth used by the received byte throughput for traffic received by the computer during the polling time period. Percentage of connection bandwidth used by byte throughput for traffic sent and received over the polling time period. The number of bytes sent to the total number of bytes sent on the connection so far. Cumulative, can be reset. The number of bytes received so far the total number of bytes received on the connection. Cumulative, can be reset. Total bytes The total number of bytes sent and received on the connection so far. Cumulative, can be reset. Number of bytes sent /Interval The total number of bytes sent on the connection during the polling time period. Bytes Received/Interval The total number of bytes received on the connection during the polling time period. Bytes/Interval The total number of bytes sent and received on the connection during the polling interval. The total number of bytes sent by a higher-level protocol request to a unicast address than the unicast number. The value includes packets that have been discarded or not sent. The total number of bytes received by the protocol request from a unicast address at a higher level of the incoming unicast number. The total number of unicast numbers sent so far and the number of unicast received. The total number of bytes sent to the subnet unicast address by a higher-level protocol request over the connection during the polling time interval. The total number of bytes received by the unicast/interval transmitted from the subnet unicast address to the higher-level protocol through the connection within the polling interval. The total number of "sent unicast" and "received unicast" for this connection during the polling time interval for unicast/interval. The total number of bytes sent to the non-subnet unicast address by the higher-level protocol request so far through the connection. The total number of bytes received from non-subnet unicast addresses to the higher-level protocol through the connection so far. The total number of non-unicast numbers so far "sent non-unicast" and "received non-unicast number". The total number of bytes sent to the non-subnet unicast address by a higher-level protocol request during the polling interval over the non-unicast number/interval transmitted by the connection. The total number of bytes received by the non-unicast number/interval transmitted from the non-subnet unicast address through the connection to the higher-level protocol within the polling interval. Non-unicast number/The total of "non-unicast" and "received non-unicast" periods within the polling interval.
