Task Switcher
is the common name for a keyboard shortcut that has been in Microsoft Windows since Windows 2.0 (1987). This shortcut switches between application-level Window (computing), windows without using the mouse; hence it was named ''Task Switcher'' (''Flip'' in Windows Vista). orders windows by Common menus in Microsoft Windows#Most Recently Used menu, most recently used, thus repeated keystrokes will switch between the two most recent tasks. It can also be used alternate between a full-size window and the desktop. The window environment maintains a Z-order list of top-level windows (tasks) with the most recently used tasks at the front and the desktop at the bottom, so the most recently used tasks can be switched to the most quickly. The keyboard combination has also been incorporated in other operating systems and desktop environments such as KDE, Xfce, and GNOME. iOS and macOS have similar functionality by pressing but that switches ''applications'' rather than ''windows''.

Alt Key
The Alt key (pronounced or ) on a computer keyboard is used to change (alternate) the function of other pressed keys. Thus, the Alt key is a modifier key, used in a similar fashion to the Shift key. For example, simply pressing ''A'' will type the letter 'a', but holding down the Alt key while pressing ''A'' will cause the computer to perform an function, which varies from program to program. The international standard ISO/IEC 9995-2 calls it ''Alternate key''. The key is located on either side of the space bar, but in non-US PC keyboard layouts, rather than a second Alt key, there is an ' Alt Gr' key to the right of the space bar. Both placements are in accordance with ISO/IEC 9995-2. With some keyboard mappings (such as US-International), the right Alt key can be reconfigured to function as an AltGr key although not engraved as such. The standardized keyboard symbol for the Alt key, (which may be used when the usual Latin lettering “Alt” is not preferred for labeling ...

Active Window
A window manager is system software that controls the placement and appearance of windows within a windowing system in a graphical user interface. Most window managers are designed to help provide a desktop environment. They work in conjunction with the underlying graphical system that provides required functionality—support for graphics hardware, pointing devices, and a keyboard—and are often written and created using a widget toolkit. Few window managers are designed with a clear distinction between the windowing system and the window manager. Every graphical user interface based on a windows metaphor has some form of window management. In practice, the elements of this functionality vary greatly. Elements usually associated with window managers allow the user to open, close, minimize, maximize, move, resize, and keep track of running windows, including window decorators. Many window managers also come with various utilities and features such as task bars, program launch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Windows XP
Windows XP is a major release of Microsoft's Windows NT operating system. It was released to manufacturing on August 24, 2001, and later to retail on October 25, 2001. It is a direct upgrade to its predecessors, Windows 2000 for high-end and business users and Windows Me for home users, available for any devices running Windows NT 4.0, Windows 98, Windows 2000 and Windows Me that meet the new Windows XP system requirements. Development of Windows XP began in the late 1990s under the codename "Neptune", built on the Windows NT kernel explicitly intended for mainstream consumer use. An updated version of Windows 2000 was also initially planned for the business market. However, in January 2000, both projects were scrapped in favor of a single OS codenamed "Whistler", which would serve as a single platform for both consumer and business markets. As a result, Windows XP is the first consumer edition of Windows not based on the Windows 95 kernel and MS-DOS. Windows XP removed suppo ...

Virtual Network Computing
Virtual Network Computing (VNC) is a graphical desktop-sharing system that uses the Remote Frame Buffer protocol (RFB) to remotely control another computer. It transmits the keyboard and mouse input from one computer to another, relaying the graphical-screen updates, over a network. VNC is platform-independent – there are clients and servers for many GUI-based operating systems and for Java. Multiple clients may connect to a VNC server at the same time. Popular uses for this technology include remote technical support and accessing files on one's work computer from one's home computer, or vice versa. VNC was originally developed at the Olivetti & Oracle Research Lab in Cambridge, United Kingdom. The original VNC source code and many modern derivatives are open source under the GNU General Public License. There are a number of variants of VNC which offer their own particular functionality; e.g., some optimised for Microsoft Windows, or offering file transfer (not part of V ...

Sysinternals
Windows Sysinternals is a website that offers technical resources and utilities to manage, diagnose, troubleshoot, and monitor a Microsoft Windows environment. Originally, the Sysinternals website (formerly known as ntinternals) was created in 1996 and was operated by the company Winternals Software LP, which was located in Austin, Texas. It was started by software developers Bryce Cogswell and Mark Russinovich. Microsoft acquired Winternals and its assets on July 18, 2006. The website featured several freeware tools to administer and monitor computers running Microsoft Windows. The software can now be found at Microsoft. The company also sold data recovery utilities and professional editions of their freeware tools. Winternals Software LP Winternals Software LP was founded by Bryce Cogswell and Mark Russinovich, who sparked the 2005 Sony BMG CD copy protection scandal in an October 2005 posting to the Sysinternals blog.

Winlogon
In computing, Winlogon (Windows Logon) is the component of Microsoft Windows operating systems that is responsible for handling the secure attention sequence, loading the user profile on logon, and optionally locking the computer when a screensaver is running (requiring another authentication step). The actual obtainment and verification of user credentials is left to other components. Winlogon is a common target for several threats that could modify its function and memory usage. Increased memory usage for this process might indicate that it has been "hijacked". In Windows Vista and later operating systems, Winlogon's roles and responsibilities have changed significantly. Overview Winlogon handles interface functions that are independent of authentication policy. It creates the desktops for the window station, implements time-out operations, and in versions of Windows prior to Windows Vista, provides a set of support functions for the GINA and takes responsibility for confi ...

Task Manager
In operating systems, a task manager is a system monitor program used to provide information about the processes and applications running on a computer, as well as the general status of the computer. Some implementations can also be used to terminate processes and applications, as well as change the processes' scheduling priority. In some environments, users can access a task manager with the Control-Alt-Delete keyboard shortcut. Task managers can display running services ( processes) as well as those that were stopped. They can display information about the services, including their process identifier and group identifier. Common task managers * Activity Monitor, included in macOS * Conky, for the X Window System * htop, for the Unix shell * KDE System Guard, included in KDE * nmon, for Linux and AIX * ps, for the Unix shell * Task Manager, included in Windows * tasklist, for DOS * top A spinning top, or simply a top, is a toy with a squat body and a sharp point at t ...

Control-Alt-Delete
Control-Alt-Delete (often abbreviated to Ctrl+Alt+Del, also known as the "three-finger salute" or "Security Keys") is a computer keyboard command on IBM PC compatible computers, invoked by pressing the Delete key while holding the Control key, Control and Alt key, Alt keys: . The function of the key combination differs depending on the context but it generally interrupts or facilitates interrupting a function. For instance, in pre-boot environment (before an operating system starts) or in DOS, Windows 3.0 and earlier versions of Windows or OS/2, the key combination Reboot (computing), reboots the computer. Starting with Windows 95, the key combination invokes a task manager or security related component that facilitates ending a Windows session or killing a Hang (computing), frozen application. History The Reboot (computing), soft reboot function via keyboard was originally designed by David Bradley (engineer), David Bradley. Bradley, as the chief engineer of the IBM Personal ...

CSRSS
Client Server Runtime Subsystem, or csrss.exe, is a component of the Windows NT family of operating systems that provides the user mode side of the Win32 subsystem and is included in Windows NT 3.1 and later. Because most of the Win32 subsystem operations have been moved to kernel mode drivers in Windows NT 4 and later, CSRSS is mainly responsible for Win32 console handling and GUI shutdown. It is critical to system operation; therefore, terminating this process will result in system failure. Under normal circumstances, CSRSS cannot be terminated with the ''taskkill'' command or with Windows Task Manager, although it is possible in Windows Vista if the Task Manager is run in Administrator mode. On Windows 7 and later, Task Manager will inform the user that terminating the process may result in system failure, and prompt if they want to continue. In Windows NT 4.0 however, terminating CSRSS without the Session Manager Subsystem (SMSS) watching will not crash the system. However in Wi ...

Windows Explorer
File Explorer, previously known as Windows Explorer, is a file manager application that is included with releases of the Microsoft Windows operating system from Windows 95 onwards. It provides a graphical user interface for accessing the file systems. It is also the component of the operating system that presents many user interface items on the screen such as the taskbar and desktop environment, desktop. Controlling the computer is possible without Windows Explorer running (for example, the command in Task Manager on NT-derived versions of Windows will function without it, as will commands typed in a command prompt window). Overview Windows Explorer was first included with Windows 95 as a replacement for File Manager (Windows), File Manager, which came with all versions of Windows 3.x operating systems. Explorer could be accessed by double-clicking the new My Computer desktop icon or launched from the new Start Menu that replaced the earlier Program Manager. There is also a s ...
