ReactOS is a free and open source implementation of the Windows NT architecture, which intends to provide support for existing applications and drivers, outside of the control of Microsoft.
The
release of ReactOS 0.4 [techrepublic.com] brings improved file system support, including native, out-of-the-box support for ext2, ext3, and ext4, as well as read-only support for NTFS.
Additionally, the bundled version of UniATA was updated to add better support for SATA and PATA devices. Support was generally improved for third-party device drivers, making it substantially easier to install and use real hardware, as opposed to just virtual machines like VirtualBox.
