Windows shortcut to activate (bring to front) the next open window

Sometimes you need to see one by one all the windows of your open programs and explorer panes, just like you activate each browser tab by pressing Ctrl+Tab.

To activate each one of your open windows just use the Alt + Esc shortcut.

If your keyboard includes a NumPad you can have this one-by-one activation with just a single keyboard button, ‘traveling’ to your open windows even more easily, with NumPad Transformer.
