I'm not so sure if this is RTM (quoted from the Blogging Windows blog)... Or, maybe it is RTM, in the sense that it is handed out to OEMs to pre-install on new machines. But maybe coming July 29 we'll see a newer build already. Now I guess I'm gonna wait until then because I don't want to go through the clean install setup hassle two times in two weeks (except for a test PC).
Anyone tried upgrading a retail Windows 7/8 to this yet and opting out of insider to see activation status?
