Download ReactOS Builds

ReactOS Builds are automatically built by our BuildBot each time a change is committed to the ReactOS Repository. This way, they incorporate latest fixes. However, they are not as thoroughly tested as the release builds. You may find regressions and bugs.

You can enter a revision number (e.g. eb1fd0c) or a revision range (e.g. 3b3c515-eb1fd0c)


  • Boot CD - Boot CDs are designed to install ReactOS onto an HDD and enjoy the new features since last release. You will need the ISO only for the installation. This is the recommended variant to install into a VM (VirtualBox, VMWare, QEMU).
  • Live CD - Live CDs allow you to use ReactOS without installing it. It can be used to test ReactOS in case your HDD is not detected during installation, or if you have no alternative system/VMs to install it on.
  • Debug - Debug versions include debugging information, use these versions to test, produce logs and report bugs. This is the recommended variant to install to report bugs.
  • Release - Release versions include no debugging information. These versions are smaller, but cannot be used to produce logs.
