    Great project! Let's bring open source to legacy applications. There's no excuse for not going Libre now.

    My gosh! These trolls that don't yet comprehend that ReactOS is for testing and on virtual systems only. It is alpha grade software... The interface is as expected, the functionality is the same, amazing progress. Will keep testing until it reaches beta! 0.4.3 - Well done!
