However, ReactOS can perform multiprocessing to allow many processes (programs) to run concurrently. Even if the PC has multiple processors or multiple cores, ReactOS will use only one core. Multiple processors are not supported at this time.

ATI GPU and CardBus drivers are not working.

Ethernet driver does work, audio driver works as well but needs portcls.sys from Windows XP/2003 and is unstable (ReactOS asserts after playing sound). push locks, guarded/fast mutexes, executive resources, many internal component locks etc.) Doesnt work very well, ReactOS has stability issues due to low amount of system memory.

Auto Boost (which in modern Windows is used in many synchronization primitives, e.g.Swap the entire process working set (new swap file).Shared ready queues for processor groups.Object-less waiting by thread ID (which in modern Windows implements many synchronization primitives).New enhanced kernel timer environment (high-resolution, finite, idle-resilient, no-wake).Core parking support (Core Parking Engine).Windows Hardware Error Architecture (WHEA).Windows Diagnostics Infrastructure (WDI).Uses Time Stamp Counter to track CPU cycles during thread runtime (cycle-based scheduling).Windows To Go (ReactOS has LiveCDs instead).exFAT (Extended File Allocation Table).Deployment Image Servicing and Management (DISM).Address Space Layout Randomization (ASLR).Windows optional component setup tool (Ocsetup.exe).User Interface Privilege Isolation (UIPI) see: ChangeWindowMessageFilter.Background Intelligent Transfer Service (BITS) (optional, stuff that would be nice to have).MUI Support (An alternative is worked on by Stefan Fulea- see CORE-10335).Error Reporting (Would be tremendously helpful to development) ( CORE-8269).System Optional Components Manager (sysocmgr.exe).Window ghosting(A window manager feature that lets the user minimize, move, or close the main window of an application that is not responding) – see CORE-11944.Image Mastering API (needed for many cd writing applications).Data Protection API (required for IE 7+).System File Checker (nice, but not absolutely needed).

Aside: There are no "free" compilers for 16bit Windows NE style code as of 2018). (A partial implementation of NTVDM exists.
