== <span style="color:green">'''Multiprocessing'''</span> ==
 +
Multiple processors are not supported at this time. Even if the PC has multiple processors or multiple cores, ReactOS will use only one core.
 +
 
 +
However, ReactOS can perform [https://www.webopedia.com/TERM/M/multiprocessing.html multiprocessing] to allow many processes (programs) to run concurrently.

This page contains a list of APIs, COM interfaces, drivers, application, extensions or other functionality that Windows has but ReactOS does not. There are other similar pages in this wiki that might help, e.g. Version Status and Roadmap. This page is intended as a list of general tasks that need to be done in ReactOS. If a certain component already exists, consider filing a bug report.

Statuses: planned, implementation started, implementation finished.

General

  • Boot from non-primary/logical/secondary partition; Boot from some primary partitions
  • Automatic Updates
  • Search [1]
  • User Login
  • WMI [2]

  • LSASS [6]
  • Multi user support
  • Multi session support
  • Fast User Switching
  • LDAP/ActiveDirectory [7]
  • Task Scheduler

  • Animated Mouse Cursors (CORE-14166)
  • Security Support Provider Interface (and the MS provided default packages) [9]
  • NTFS
  • WOWEXEC to run older Windows applications, based on 16 bit code. (A partial implementation of NTVDM exists. Aside: There are no "free" compilers for 16bit Windows NE style code as of 2018).

Multiprocessing

Multiple processors are not supported at this time. Even if the PC has multiple processors or multiple cores, ReactOS will use only one core.

However, ReactOS can perform multiprocessing to allow many processes (programs) to run concurrently.

In GSoC 2021 student Justin Miller planning to complete Symmetric Multiprocessing (SMP).

Drivers

Display

  • Internet Protocol Version 6 [52]
  • DHCP Server
  • SMB Filesystem Server/Client [53]

  • Tunnel (P-t-P) Network Communication

Low Priority Framework implementations

  • MFC and Visual C support runtimes...
  • Visual Basic Runtime
  • .NET alternative such as Mono
  • Windows Runtime
