It seems that a couple of things are set to happen on July 29 in the Windows world. Windows 10 will be officially one year old. Microsoft will stop nagging people to upgrade to Windows 10 and Windows 10 will, once and for all, no longer be a free upgrade. But it seems that Microsoft has also schedule that day to be the RTM (release to market) launch of the Windows 10 Redstone 1 update, a.k.a. the Anniversary update. It makes sense, considering the name, but now there is more or less some confirmation about it.
