About this tag
The open source operating systems tag on WindowsForum.com follows projects that offer alternatives to or reimplementations of Windows, with ReactOS as the clearest recurring example. Discussion centers on practical engineering milestones, such as ReactOS gaining the ability to install and run from an NTFS partition after nearly a decade of work, along with added NTFS formatting support that aims for Windows compatibility. Threads also weigh what remains unfinished, including driver limitations that keep such systems short of everyday desktop readiness. Coverage suits readers tracking filesystem compatibility, driver maturity, and the slow progress of community-built operating systems.

    ReactOS can now be installed on an NTFS partition and run from it. The project has been working toward this for nearly a decade, and it is a real milestone. It is also a long way from a finished filesystem. What actually changed ReactOS said on X that, after nearly a decade, its NTFS driver got...
