My releases come from Technet so are as "legal" as they get. I don,t know if it is an answer posed by the questions above, but to the best of my knowledge, apart from 5 "test" updates, there have been none, specifically for the OS, only for add-ons such as the graphics card etc.. I wiped 7000 some time ago, so am only, for this thread, referring to later builds, but I do seem to recall 2 very minor updates for that release, shortly after it was availabl?.
I can't offer anything for watrmilan's problem. Maybe you left the activation too long after the installation?
