Today, Microsoft posted their first public post-RC1 build of Windows Vista to beta testers. This build, 5728 includes a number of bug fixes and interface tweaks but nothing major in terms of functionality or usability. This is an interesting number since the 5700 range has been reserved for the final, Release To Manufacturing, the final build of Vista that goes to DVD reproduction and then ships to retailers worldwide. This indicates that Vista could be declared "done" by the end of next month.
Is Vista ready for release? RC1 is a marked improvement, but personally I'm still having issues where PS/2 keyboards and mice just don't load. Is 5728 a major improvement? Will the bugs and incompatibilities testers are reporting be addressed in time? Microsoft is running rapidly out of time if it wishes to make its self-imposed deadline.
