Microsoft will begin testing the new privacy-settings upgrade experience with its Windows Insider testers today, March 1, officials said, making sure it's working well before the Creators Update starts rolling out to the mainstream (something sources have said will happen in April 2017).
Today, March 1, Microsoft will make the new privacy upgrade process available to Insiders for testing via a "quest" in the Feedback Hub. In order to test this, Windows Insiders will need to roll back to the Windows 10 Anniversary Update, get a notification about the Creators Update's availability, and then select privacy settings. (Screenshots of what this new privacy experience for upgraders will look like are embedded in this post above.)
Microsoft officials noted that Microsoft also will be making other modifications around user controls with the Windows 10 Creators Update. Users will get more control over when Windows 10 installs feature upgrades like the Creators Update and cumulative security/feature rollups, starting with the coming release.
Microsoft also is adding the ability to reschedule an update if a user's original choice of time isn't convenient. A new "Snooze" capability allows users to pause the update process completely for three days (but can be hit repeatedly for repeated delays).
