though i am not certain; but mostly because of registering for the Tech Preview and then downloading the Trial; that I think prompted Microsoft to offer me Office 2010 Pro at zero financial cost At the moment I dont seem to find the link they sent; but eventually it took me to a (sort of) order page :prop: at zero value :prop: The initial mail offering the bounty was so innocuous that only recently [two months back] did I notice it in my Inbox and got to the zero value "Order". Would not believe it, had it not happened to me. But then again, one never knows.
