Operating systems did jobs by running processes and tasks. One of the primary duty for an operating system is the management of processes. All operating systems have a different type of task manager. Windows have built-in task manager maned
Task Manager . In this tutorial, we will look detailed about Windows Task Manager.
Start Task Manager
There are different ways to start Task Manager. One way is using
Run command box providing
taskmgr like below.
Another way is
Right click to Task Bar and click to the
Task Manager .
Applications tab provides currently running User space graphical applications. In a system actually there a lot of applications running but only some of them are GUI applications directly interacted by the user. This tab lists these applications. We can see from the example that the user is currently running
Mozilla Firefox and
Google Chrome .
Processes tab will list all processes that are running on the system. Some processes may be running on the background. There are following information about processes
Image Namecolumns show processes executable name
User Namecolumn shows the user who owns and started the process
CPUcolumn shows the CPU usage percentage of the process
Memorycolumns show the memory usage of the process
Descriptioncolumn show more detail about the process
Add New Column
We can also add a new column to get different information about processes. In order to add column we need to list available columns with
Select Columns... like below.
After that, windows like below will be shown
In this window, we can select which columns we want to list just by checking. Important of the columns are;
- CPU Time
- I/O Reads
- I/O Writes
- Command Line
Show Processes From All Users
By default task manager will only list processes owned by the current user. In our example the current user is
ismail . But we may need other user processes to list. This can be done with the checkbox below the left corner. This will list all users like
LOCAL SERVICE and other normal users.
There is also information about total process numbers, total CPU usage, and memory usage.
Services or daemon generally works background. Services do not need any GUI. Services also run always not like a process. Because the process starts and ends in some time. We can list services with Task Manager in the
Namecolumn shows the name of the service
PIDcolumn shows the process ID of the service
Descriptioncolumn shows more information about the service
Statuscolumn shows the current working condition like
Groupcolumn shows a related group of the service
Task Manager also provides information about the system resources. Task Manager provides load information about CPU, Memory. There are the following information;
- CPU Usage
- CPU Usage History
- Physical Memory
In the networking tab, the network interfaces listed as graphs and their network speed and usage percentage are shown. There is also information like network interface connection status, link speed
In the User tab currently, connected users are shown. In this example, we see that the use named
ismail is connected to the local system with the ID 1 and session type is console which means a local desktop session.
Usercolumn shows account computer and name
IDcolumns show user connection ID
Statuscolumn shows current user status whether is connected or not
Sessioncolumns show where the user connected. This can be
All ways On Top
If we want to Task Manager window always stay on top we can set this from
Options a menu like below. This will always show the Task Manager on the top of the open windows and applications even they are opened later than Task Manager.
