Task manager is the default monitor of Windows systems. We can control many system activities like ‘End Process’ using task manager.
These are 6 methods to open your task manager normally.
Ø Just Press Control, Shift, and Escape keys from your keyboard simultaneously (‘Ctrl’ + ‘Shift’ + ‘Esc’). You will get your Task manager.
Ø Right click on ‘Taskbar’, from given menu, click on ‘Start Task Manger’.
Ø Just press Alt, Control and Delete keys simultaneously (‘Alt’ + ‘Ctrl’ + ‘Delete’). Now you will get about 5 options. Click on ‘Start Task Manager’ (may be at last).
Ø Open run, (Window key + 'R'), then type: taskmgr and press OK button.
Ø Type this on Run and press OK: C:\Windows\System32\taskmgr.exe
Ø Search for taskmgr in search box in task menu. Then open taskmgr.
All above methods are working will on latest operating system such as Windows Vista, Windows 7 and Windows 8. But, in Windows XP, first method will not work in some service packs and third method will give you Task Manager directly.
