I posted a good while ago about ReactOS, an open source Windows NT based OS, capable of running all programs that Windows can run. I've already expressed my undying fascination and praise for the project and I still feel the same way. I wondered if it was going to die out, which would be terrible, but last month, ReactOS 0.3.1.2 was released! Granted, this still puts them behind their tentative schedule, but it definitely is a very good sign when it comes to the project. Like I said before, reverse engineering an OS is no easy task, and I still laud the ReactOS team for their initiative. Hopefully they will keep up the amazing work.
