Software giant Microsoft commenced the distribution of its major Windows 10 upgrade for 2016 -- the ‘Anniversary Update’ -- to customers on Tuesday, August 2, 2016. The rollout of the Anniversary Update was started by Microsoft at around 1 pm ET.

The Anniversary Update is being rolled out to Windows 10 users across different devices through the update service of the operating system.

The Windows 10 Anniversary Update marks the commemoration of the first anniversary of Windows 10 OS, the inaugural edition of which was released on July 29, 2015. The Anniversary Update is officially tagged as version ‘1607’ to denote ‘July 2016.’ The build number assigned to the upgrade is 14393.10.

In announcing the commencement of the rollout of the Windows 10 Anniversary update, Microsoft said that though Windows 10 users can download the upgrade with immediate effect by manually triggering a check for updates in the Settings panel, the majority of the users will receive the update according to the company’s schedule.

Towards that end, Microsoft executive Michael Fortin said in a Tuesday blog post: “[The Anniversary Update] will roll out automatically to you through Windows Update if you've chosen to have updates installed automatically on your device.”
