  • •ReactOS can now be installed on NTFS partitions, a major milestone for the project.
  • •The new NTFS driver lacks caching, journaling, and security support, impacting performance.
  • •Users are cautioned about potential undiscovered bugs in the new driver.

ReactOS has announced that its NTFS file-system driver has matured, allowing the open-source operating system to be installed directly on NTFS partitions. This significant development brings ReactOS closer to its goal of achieving binary compatibility with Windows Server 2003. Previously, installations required a FAT32 partition, which posed limitations. However, the new driver still lacks features such as caching, journaling, and security support, which may lead to performance issues and undiscovered bugs. Users are advised to proceed with caution when using this new functionality. The announcement was made on October 19, 2026, and is reported by both Ars Technica and Phoronix.
