The functions of task manager is to monitor the applications, processes, services, CPU performance and current user of the system.
As default only five columns are displayed in task manager, but you can include more tab to check more operations.
To include more tabs, open task manager – click view – select coloums where you can select the columns which you want to include.
List of coloums and its descriptions,
* PID (Process Identifier): An unique ID number assigned by Windows to every process which helps processor to identify each process separately.
* User Name: The user account under which the process is running.
* Session ID: It is used to identify the owner of the process in case if multiple users are logged on, each user has its own unique session ID.
* CPU Usage: The percentage of time that a process used the CPU.
* CPU Time: The total processor time, in seconds, used by a process since it started.
* I/O Reads: The number of read input/output operations generated by the process, including file, network, and device I/Os. I/O Reads directed to CONSOLE (console input object) handles aren’t counted.
* I/O Writes: The number of write input/output operations generated by the process, including file, network, and device I/Os. I/O Writes directed to CONSOLE (console input object) handles aren’t counted.
* I/O Other: The number of input/output operations generated by the process that are neither a read nor a write, including file, network, and device I/Os. An example of this type of operation is a control function. I/O Other operations directed to CONSOLE (console input object) handles aren’t counted.
* I/O Read Bytes: The number of bytes read in input/output operations generated by the process, including file, network, and device I/Os. I/O Read Bytes directed to CONSOLE (console input object) handles aren’t counted.
* I/O Write Bytes: The number of bytes written in input/output operations generated by the process, including file, network, and device I/Os. I/O Write Bytes directed to CONSOLE (console input object) handles aren’t counted.
* I/O Other Bytes: The number of bytes transferred in input/output operations generated by the process that are neither a read nor a write, including file, network, and device I/Os. An example of this type of operation is a control function. I/O Other Bytes directed to CONSOLE (console input object) handles aren’t counted.
* Memory Working Set: Amount of memory in the private working set and shared by the other processes.
* Memory Peak Working Set: Maximum amount of working set memory used by the process.
* Memory Working Set Delta: Amount of change in working set memory used by the process.
* Memory Private Working Set: Subset of working set that specifically describes the amount of memory a process is using that can’t be shared by other processes.
* Memory Commit Size: Amount of virtual memory that’s reserved for use by a process.
* Memory Paged Pool: Amount of pageable kernel memory allocated by the kernel or drivers on behalf of a process. Pageable memory is memory that can be written to another storage medium, such as the hard disk.
* Memory Non-paged Pool: Amount of non-pageable kernel memory allocated by the kernel or drivers on behalf of a process. Non-pageable memory is memory that can’t be written to another storage medium.
* Page Faults: The number of page faults generated by a process since it was started. A page fault occurs when a process accesses a page of memory that’s not currently in its working set.
* Page Fault Delta: The change in the number of page faults since the last update.
* Base Priority: A precedence ranking that determines the order in which the threads of a process are scheduled.
* Handles: The number of object handles in a process object table.
* Threads: The number of threads running in a process.
* USER Objects: The number of USER objects currently being used by the process. A USER object is an object from Window Manager, which includes windows, menus, cursors, icons, hooks, accelerators, monitors, keyboard layouts, and other internal objects.
* GDI Objects: The number of objects from the Graphics Device Interface (GDI) library of application programming interfaces (APIs) for graphics output devices.
* Image Path Name: The location of the process on the hard disk.
* Command Line: The full command line specified to create the process.
* User Account Control (UAC) Virtualization: Identifies whether User Account Control (UAC) virtualization is enabled, disabled, or not allowed for this process. UAC virtualization redirects file and registry write failures to per-user locations.
* Description: The description of the process. It helps beginners to identify the process easily.
* Data Execution Prevention: Whether data execution prevention is enabled or disabled for this process.
