MS-DOS (Microsoft Disk Operating System) is a monolithic singletasking operating system developed by Microsoft between 1980 and 2000 for x86-based personal computers. It was the de facto industry standard environment on the IBM PC and its clones, although it also shipped with other x86-based computers that were incompatible with IBM.

By default, MS-DOS is driven by a command line interface – the A> or C:\> prompt shown when the command processor is ready to accept input ultimately became one of the unofficial symbols of DOS. Several software vendors have developed programs that add a more friendly user interface to manage files and launch other programs. Microsoft itself included such a program, the MS-DOS Shell, with some versions of MS-DOS.

Processes info[edit | edit source]

(ported from an old test wiki of mines)

Here is a list of critical Windows processes that you will see on Windows NT systems. These processes more than often cannot be killed via Task Manager (unless on Vista or later). If the process's watcher is not terminated, the results listed will occur.

Credit to this blog from Mark Russinovich for the info.

  • winlogon.exe: Deals with Windows login sessions, watches lsass.exe and services.exe. Run when booting; when terminated:
    • XP: BSOD
    • Vista and up: Log off
  • smss.exe: Session manager. Watches winlogon.exe, which if not terminated first, causes BSOD. Run when logging in, when terminated:
    • XP: Does nothing
    • Vista and up: BSOD
  • csrss.exe: Client Server Runtime Subsystem. OS runs on top of this. Run when booting; when terminated, cause BSOD (STOP 0x0F4).
  • lsass.exe: Local Security Authority Subsystem Service. Verifies user logins and allows password changes. Run when logging in; when terminated, reboot computer after 1 minute.
  • services.exe: Service Control Manager. Controls all Windows services. Run when booting; when terminated, reboot computer after 1 minute.
  • explorer.exe: Windows Explorer. Holds the main interface. Run when logging in; when terminated, gets rid of Taskbar, all Window Explorer processes, and desktop icons. On Windows 8 and up, also removes background. Usually reopens if it is terminated in any way except by terminating it manually.
  • svchost.exe: Service Host. Holds user's themes. On Windows Vista and up, many instances of this process will run and they will usually relaunch if terminated. Run when booting; when terminated:
    • XP: Revert theme to lowest default
    • Vista and up: Does nothing
  • System: Holds system threads. Cannot be terminated.
  • System Idle Process: Not a real process, tracks time no thread was running. Cannot be terminated.
  • DCOM Server Process Launcher: Helps communicate the system with applications, if terminated:
    • Windows XP-7: Reboot computer after 1 minute
    • Windows 8-10: BSOD
