How to Keep Track of Open Windows in Windows 8
You don't have to keep track of all those open windows on the desktop. Windows 8 does it for you with a secret key combination: Hold the Alt key and press the Tab key, and a little bar appears, displaying the icons for all your open windows. Keep pressing Tab; when Windows highlights the icon of the window you're after, release the keys. The window pops up.
Or visit the taskbar, that long strip along the bottom of your screen. The taskbar lists the name of every open window. Click the name of the window you want, and that window hops to the top of the pile.
If a program icon on the taskbar contains several open windows — you're simultaneously editing several documents in Microsoft Word, for example — right-click the Microsoft Word icon. A pop-up menu appears, letting you click the document you want to access.
Can't find a previously opened Start screen app? Hold down the Windows key and press the Tab key: Thumbnail images of all your open apps appear on a strip along the screen's left edge. Keep pressing the Tab key until you've highlighted the desired app; let go of the Tab key, and the selected app fills the screen.
