A little unfair? It does state clearly on the download page it is a release candidate and has been made available for IT pros to test etc. Just about all software companies provide beta/RC code. I guess this is also one of the downsides of search engines in that they take you straight to a page that might be read out of context.i just uninstalled it, using the programs and features bit, looks like it has been wiped off.
why would microsoft put something on their website if it wasn't good?
it just boggles the mind. they are supposed to be restoring their reputation.
