Just a couple days after the Creators Update started to roll out to all Windows 10 PCs this April, Microsoft made an important announcement concerning its update schedule for Windows 10: going forward, the company is committed to Windows 10, Office releases twice a year, in March and September. As a result, Microsoft said at the time that the upcoming Windows 10 Fall Creators Update “will be targeted for September 2017.”
As you may know, the current version of Windows 10 (the Creators Update) is also codenamed version 1703, as it went RTM in March of this year. As it turns out, the upcoming Fall Creators Update should unsurprisingly be codenamed version 1709, and Twitter user WZor already spotted the version number on Microsoft’s Windows IT Center (via Neowin).

So yes, if everything goes as expected, we should see the Windows 10 Creators Update go RTM in September, though Microsoft may choose to start rolling out the update to everyone the following month (just like it did with the version 1703). However, you may remember that it was possible to install the latest major release right in March, by using either the Windows Insider Program, official ISOs or Microsoft’s Upgrade Assistant. It remains to be seen how Microsoft will proceed this time, but if you’re a Windows Insider you’re pretty much guaranteed to get access to the RTM version of the Fall Creators Update before everyone else.
