More Windows 9 rumors: one-click upgrades, interactive tiles, notification center

Rumors about the next major version of Windows continue to trickle out in the run up to an anticipated public preview in September.

Neowin reports that internal builds of the operating system currently sport a one-click upgrade feature to update from one build to the next. While there’s no guarantee that such a feature will necessarily ship, it would be consistent with Microsoft’s move to more rapid releases and continuous improvement rather than infrequent major updates.
