Microsoft is preparing for the next big update for Windows 10, that's the Creators Update from the Redstone 2 branch. If you are running Windows 10, you might have already started receiving the promotional message on your Windows Update page.
This message appears on the Windows Update page for the users who are running the latest version of the Windows 10 anniversary update.
If you are running Windows 10 Anniversary Update and installed the latest updates, you will now see a message in the Windows Update settings page that says "Good news! The Windows 10 Creators Update is on its way".
If you don't find it, go to Settings, click on Update & security and then click on the Check for updates button. The system will then check for updates and install them. Once you restarts your system, go to the same page to find this message. Clicking on the link "Yes, show me how" will open Microsoft Edge with a thank you page.
Windows 10 Creators Update will be released in waves and will be free for users running the anniversary update. Signing up for it now will give you higher preference than others. Stay tuned for more posts coming up on this topic. If you are a Windows Insiders, you have already tried the new features that coming with it, which is planned to be release in early April 2017.
