These are the most frequently encountered known issues.
Contents
Audio
Code supporting audio is unstable. Presently, ReactOS's audio targets features of Microsoft Windows XP and Server 2003.
Forum discussion, Creative EAX Aureal 3D and others in old games
DirectX
DX9 functions but at this time uses ReactOS's OpenGL acceleration support with the Wine project's wrapper code to provide DX9 support.
Drivers
Drivers, Built in
Only a basic set of drivers are provided by ReactOS. Drivers for additional devices and drivers tailored for devices such as high-performance video cards must be installed manually.
Drivers, Manual installation of
Manual installation of some drivers is not always possible. The ReactOS driver stack may be missing functions that a third-party driver requires for its installation.
Drivers, Software for installation of
Software that automates the installation of hardware device driver software usually fails. Install drivers manually.
File Systems
EXT2
ReactOS can read and write ext2. However, support is not yet complete enough to allow installation of ReactOS on ext2 file systems.
FAT32
Well supported. At this time ReactOS can only be installed on a FAT32 file system.
Installable file system (IFS)
Not functional at this time. The ReactOS project intends for all file system drivers shipped with ReactOS to use IFS.
NTFS
ReactOS can read NTFS. Write capability is being worked on. Much more debugging is required. Do not write on NTFS storage devices if any data on the device is valuable. NTFS support is not yet complete enough to allow installation of ReactOS on NTFS file systems.
UDF
UDF support (required for DVDs) is not yet bug free. May have problems when starting an executable file from UDF disc. May have to manually eject disc from drive.
Other
Why the ReactOS Project will not work on NTFS/ZFS/Reiser4/whatever right now
Installation
Installation from USB drives
Cannot install ReactOS from USB drives.
Installation, required file system for
ReactOS can only install on FAT32 file systems at this time.
Mouse
Mouse pointer speed adjustment
Mouse pointer speed adjustment is not supported at this time.
Mouse, USB device
See USB.
Multiprocessing
Not supported at this time. Even if the PC has multiple processors or multiple cores, only one core will be used.
Network
Executable files cannot be run from network shares. This is believed to be due to missing functionality in the cache subsystem in the kernel.
Built-in NIC drivers
ReactOS's network interface controller (NIC) driver support (i.e., Ethernet functionality) is only implemented for NICs based on the Realtek 8139 device. Clever people might be able to manually install the drivers for other NICs on their PCs. (There are no formal instructions to do this.)
Wi-Fi
Only Wired Equivalent Privacy (WEP) is supported at this time.
Printing
The printing stack is incomplete. May be able to send raw ASCII text through parallel port, nothing else. For the details of what is currently missing, please see the Printing page.
Remote Procedure Call
Memory leak
Most Remote Procedure Call (RPC) client processes leak memory.
Serial Port
Debugger connection
Debugger connection from target PC under test to host PC via null-modem cable consumes serial port COM1.
USB
USB stack is not yet fully functional. Attached USB devices including USB keyboards, mice, and touch pads (even if built into a laptop) may prevent ReactOS from booting or cause a bug check if attached after ReactOS is booted. Most USB keyboards and mice will not work with ReactOS.
