Taskbar task bar is available when pc starts but later it is not visible

Press ctrl+esc to see if the start menu pops up, if it does not then proceed by trying the following steps below.

Make sure explorer.exe is still running:
Press ctrl+alt+delete to get into Task Manager and do File -> New Task -> explorer.exe -> OK

Otherwise check to see if your task bar is auto hiding:
Move the cursor to all four edges of the screen in an attempt to locate the hiding task bar. If the task bar does pop up, right click on it and press properties. Proceed by unchecking Auto-hide the taskbar under the Taskbar tab and pressing Apply and OK.

If all else fails, try rebooting the PC.

Padmajam,
Someone has played a prank on you. If you take the mouse pointer to the bottom edge the task bar will come on. When it comes on right click on it in the blue space and select the properties. Unclick the box for "Auto hide the Task Bar". And your task bar will be visible to you till someone hides it again.

mine does this with windows 7, right click on desktop and open 'personalize' then open 'taskbar and start menu'
From here choose to move your taskbar location to the side of the screen and click apply. it should return, then just tell it to go back to the bottom.

It seems your task bar has been configured for auto hide just move your cursor to the task bar area it will come up and right click on it go to properties and uncheck autohide
Kindly rate my solution

Open task bar properties, from control panel, choose taskbar and start menu. Uncheck the check box at the bottom of the window.

drag it to the right then to bottom. first make sure its not "locked" by right clicking it.

you have to right click on the taskbar and select lock the taskbar

hi gauravas, just right click on the desktop then select arrange icon by then goto right pane and check the show desktop icon.
for stable of start menu rotate your mouse to lower down of the scren then your taskbar will popup, right click on task bar and uncheck the Auto-hide the task bar.

Hi,

This may be because your task bar is set to 'auto hide' so you will have to disable it.
