Service Control Manager
Service Control Manager (SCM) is a special system process under the Windows NT family of operating systems, which starts, stops and interacts with Windows service processes. It is located in the %SystemRoot%\System32\services.exe executable. Service processes interact with SCM through a well-defined API, and the same API is used internally by the interactive Windows service management tools such as the MMC snap-in Services.msc and the command-line Service Control utility sc.exe. Terminating this file is used as a method of causing the Blue Screen of Death. Implementation The SCM executable, Services.exe, runs as a Windows console program and is launched by the Wininit process early during the system startup. Its main function, SvcCtrlMain(), launches all the services configured for automatic startup. First an internal database of installed services is initialized by reading the following two registry keys: * HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\ServiceGroupOrder\ ...

Process (computing)
In computing, a process is the instance of a computer program that is being executed by one or many threads. There are many different process models, some of which are light weight, but almost all processes (even entire virtual machines) are rooted in an operating system (OS) process which comprises the program code, assigned system resources, physical and logical access permissions, and data structures to initiate, control and coordinate execution activity. Depending on the OS, a process may be made up of multiple threads of execution that execute instructions concurrently. While a computer program is a passive collection of instructions typically stored in a file on disk, a process is the execution of those instructions after being loaded from the disk into memory. Several processes may be associated with the same program; for example, opening up several instances of the same program often results in more than one process being executed. Multitasking is a method to allow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Microsoft Press
Microsoft Press is the publishing arm of Microsoft Microsoft Corporation is an American multinational technology corporation producing computer software, consumer electronics, personal computers, and related services headquartered at the Microsoft Redmond campus located in Redmond, Washing ..., usually releasing books dealing with various current Microsoft technologies. Microsoft Press' first introduced books were ''The Apple Macintosh Book'' by Cary Lu and ''Exploring the IBM PCjr Home Computer'' by Peter Norton in 1984 at the West Coast Computer Faire. The publisher has gone on to release books by other recognizable authors such as Charles Petzold, Steve McConnell, Mark Russinovich and Jeffrey Richter. Following a deal signed in 2009, O'Reilly Media became the official distributor of Microsoft Press books. In 2014, the distributor was changed to Pearson PLC, Pearson. In July 2016, Microsoft Press editorial staff was laid off. References External links * Micr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Svchost
Svchost.exe (Service Host, or SvcHost) is a system Process (computing), process that can host from one or more Windows services in the Windows NT family of operating systems. Svchost is essential in the implementation of ''shared service processes'', where a number of services can share a process in order to reduce resource consumption. Grouping multiple services into a single process conserves computing resources, and this consideration was of particular concern to NT designers because creating Windows processes takes more time and consumes more memory than in other operating systems, e.g. in the Unix family. However, if one of the services causes an unhandled exception, the entire process may crash. In addition, identifying component services can be more difficult for end users. Problems with various hosted services, particularly with Windows Update, get reported by users (and headlined by the press) as involving svchost. The svchost process was introduced in Windows 2000, altho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Operating System Service Management
In computing, mechanisms and techniques for managing services often differ by operating system. Examples of operating system service management are: * Service Control Manager - Used by Microsoft Windows * launchd - Used by Apple macOS * systemd - Used by many Linux distributions * Upstart - Used by Google ChromeOS * Service Management Facility - Used by illumos distributions and Oracle Solaris Android init- Used by Google Android * sysvinit - Used by older Unix-like operating systems * rc.d or rcorder-based init - Used by BSD operating systems cygserver- Used by Cygwin * runit - Used by Void * OpenRC - Used by Gentoo * The GNU Shepherd - Used by the Guix System Distribution and GNU Hurd but designed to work on every POSIX-like system where Guile is available See also * init In Unix-based computer operating systems, init (short for ''initialization'') is the first process started during booting of the computer system. Init is a daemon process that continues running u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Message Passing
In computer science, message passing is a technique for invoking behavior (i.e., running a program) on a computer. The invoking program sends a message to a process (which may be an actor or object) and relies on that process and its supporting infrastructure to then select and run some appropriate code. Message passing differs from conventional programming where a process, subroutine, or function is directly invoked by name. Message passing is key to some models of concurrency and object-oriented programming. Message passing is ubiquitous in modern computer software. It is used as a way for the objects that make up a program to work with each other and as a means for objects and systems running on different computers (e.g., the Internet) to interact. Message passing may be implemented by various mechanisms, including channels. Overview Message passing is a technique for invoking behavior (i.e., running a program) on a computer. In contrast to the traditional technique of callin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
