The Windows 10 Anniversary Update is available (1607).
Windows 10 users will get it automatically this week; but you can force the update from the following link.
It is about 3.6GB download and an hour or so to upgrade.
Download was fast on a NBN 100mbps connection; but ADSL users may wish to let it happen automatically overnight.
I've updated 3 systems this morning, 2 notebooks and a desktop; (2 x home, 1 x pro); all straightforward and no issues.
