== Introduction ==

HelenOS starts into a graphical user interface, provided a usable graphical output device is found (otherwise it will start into a text console). You can move windows around, close them, resize, etc. using your mouse.

On startup you are presented with a console window (you can type commands there), a launcher window and the task bar, which allows switching between windows.

The GUI also has support for [wiki:UsersGuide/MultiSeat multiple seats].

== Window Management ==

Clicking on a window activates it and brings it to top. You can also switch between windows by pressing the corresponding button
on the task bar.

You can move a window by dragging its title bar. You can resize a window by dragging any of its corners or edges. You can
minimize, maximize or close a window by clicking the corresponding button in the title bar. To restore a minimized window, you need to find its title among the buttons in the Task Bar and click it.

You can also access the window management functions via a window's system menu. To open the system menu, click its handle, or press F10. If the window has a menu bar, you then need to press Left arrow key to select the system menu. Then press Down to open the system menu.
