Windows key

The Windows key was introduced with Microsoft's Natural Keyboard in 1994. The key was predated by the key on Apple computers in the 1980s, and before that by the (or ) key on Lisp/Unix workstation computers in the 1970s. The addition of two Windows keys and a menu key marked a change from the traditional 101 or 102-key keyboard to a 104- or 105-key layout for PC keyboards. One Windows key was placed between the left and the left and another, along with a menu key, was placed between the right (or ) and the right key. Windows 95 required the key to be on a keyboard to qualify for the addition of the "Designed for Windows" logo, and used it to open the Start menu. The key was soon added by virtually all desktop keyboard manufacturers. The first laptop to bear the Windows key was the Gateway Solo. In laptops and other compact keyboards, it is common to have just one Windows key (usually on the left side). On Microsoft's Entertainment Desktop sets, designed for Windows Vista, the Windows key is in the middle of the keyboard, below all other keys, where the user's thumbs rests. Some keyboards during the Windows Vista and Windows 7 eras featured a circular bump surrounding the logo, distinguishing it tactility. On Windows 8 tablet computers, hardware-certification requirements initially mandated that the Windows key be centered on the bezel, below the screen, except on a convertible laptop, where the button was allowed to be off-center in a tablet configuration. This requirement was relaxed in Windows 8.1, allowing the Windows key to be placed on any bezel or edge of the unit, though a central location along the bottom bezel was still preferred. == Use within Windows ==

From Windows 95 to Windows 7, tapping the Windows key by itself traditionally revealed the Windows Taskbar (if hidden) and opened the Start menu. In Windows Server 2012 and Windows 8, the key launches the Start screen but does not show the taskbar. However, this feature was added back in Windows 10. Pressing the key in combination with other keys (i.e., as a modifier key) allows the invocation of many common functions. Holding down is not a substitute for the Windows key itself in these combinations. Which Windows key combinations ("shortcuts") are available and active in a given session depends on many factors, such as active accessibility options, the type of the session (regular or Terminal Services), the Windows version and the presence of specific software, such as IntelliType, and Group Policy, if applicable. Below is a list of native shortcuts. The list is cumulative: unless otherwise noted, they were carried through to subsequent version of the operating system. Windows 95 and Windows NT 4.0 The following shortcuts are valid in Windows 95 and Windows NT 4.0. • opens the Start menu • shows the desktop (hiding even non-minimizable windows), or restores hidden windows when pressed a second time • opens Windows Explorer with folder pane on left side of window • opens Find files and folders • minimizes all windows • restores windows that were minimized with • opens the "Run Program Or File" Window • runs Utility Manager • or opens properties of My Computer • opens Windows Help • opens Find computers • cycles through taskbar buttons (this key combination is reassigned in Windows Vista and Windows 7) Windows 2000 Windows 2000 introduced the following: • locks the desktop Windows XP Windows XP introduced the following: • selects the first icon in the Notification Area • opens Search for Computers (requires Active Directory Domain Services) • locks the desktop and (if Fast User Switching is enabled) shows the user selection screen Windows XP Media Center Edition Windows XP Media Center Edition introduced: • starts Windows Media Center Windows Vista Windows Vista introduced the following: • brings the Windows Sidebar to the front • selects next Windows Sidebar gadget item, bringing all gadgets to the foreground in process.

The Windows key can also be used on other operating systems, though it usually carries a different name in them. Some cross-platform applications refer to the key as the OS key. X/Wayland (used on Linux and similar) use the keysym "Super" for the Windows key(s), and toggles the MOD4 shift bit. Most Unix desktop environments use it much like Windows, with activating a primary menu similar to the Windows Start menu, and in combination with character keys performing actions such as run-command, often with the shortcuts and actions the same as Windows for familiarity. A common action that is not shared with Windows is for the Super key to allow dragging a window around from any location without raising it. If one plugs a Windows keyboard into a macOS computer, the Windows key acts as the Command key|. As Alt key| or acts as Option key|, the physical locations of the keys that act as Command and Option are swapped. Plugging a Macintosh keyboard into a Windows (or Linux) machine does the reverse mapping and thus also swaps the Windows and Alt key locations. If one plugs a Windows keyboard into a computer running ChromeOS, the Windows key acts as the Search key| key. A standard ChromeOS keyboard has this key in the location where Caps Lock usually is. If one plugs a Windows keyboard into an Xbox 360, pressing the Windows key performs the same action as the Guide button on Xbox 360 Controller or remote controls, opening the Xbox Guide. Holding down the Windows key and pressing M opens a pop up conversation window over gameplay, if an instant message conversation is in progress. On an Xbox One or Xbox Series S/X, pressing the Windows key performs the same action as pressing the Xbox button on the controller. On a PlayStation 3 console, pressing the Windows key performs the same action as the PS Button on the Sixaxis and DualShock 3, opening the XrossMediaBar. == Licensing ==

Microsoft regulates the appearance of the Windows key logo with a specially crafted license for keyboard manufacturers. With the introduction of a new Windows logo with Windows XP, the agreement was updated to require that the new design be adopted for all keyboards manufactured after 1 September 2003. With the introduction of Windows Vista, Microsoft published guidelines for a new Windows Logo key that incorporated the Windows logo recessed in a chamfered lowered circle with a contrast ratio of at least 3:1 with respect to its background. In the Common Building Block Keyboard Specification, all CBB compliant keyboards were to comply with the Windows Vista Hardware Start Button specification beginning on 1 June 2007. == Unicode ==

The Unicode character resembles the look of the key on many keyboards. == See also ==
