 Microsoft’s regular schedule of releases for Windows 10 is expected to drop a major update in the latter stages of 2021. Despite being some way off, the Windows 10 21H2 Update, currently being referred to as ‘Sun Valley’, is shaping up to be a significant step forward for the operating system. 
Microsoft is yet to officially reveal the 21H2 update to Windows 10, but through leaks, rumors, and the Windows Insider Program, we’ll begin to piece together a good picture throughout the months leading up to its release.
With Build 2021 now finished with only a smattering of hints towards the next release of Windows, users are curious as to whether we may see 'Sun Valley' appear sooner rather than later.
It looks to be sooner, with Microsoft holding an event later this month

Windows 10 21H2 ‘Sun Valley’ release date 

Right now there is no confirmed release date for the Windows 10 21H2 ‘Sun Valley’ update. Microsoft’s release schedule for Windows 10 updates in recent times has been to push out a major update in each half of the year. 
The first update for 2021, Windows 10 21H1 has already been announced and is in the later stages of testing before release in the first half of the year. What we can safely expect is that the second update will be released between June and December. 
Windows Central reports that the internal timeline for the Windows 10 21H2 release points to October, with testing through the Windows Insider channels before then. Isolated features may appear in the Dev Channel first, with a ‘final build’ decided upon in June to then begin testing through the Beta Channel

Right now there is no confirmed release date for the Windows 10 21H2 ‘Sun Valley’ update. Microsoft’s release schedule for Windows 10 updates in recent times has been to push out a major update in each half of the year. 
The first update for 2021, Windows 10 21H1 is already out, but we can safely expect is that the second update will be released between September and December. 
It looks as though Microsoft are focusing more on having Windows 11 in a stable form, with speculation pointing towards an October release as well. So we may see two significant updates here for two operating systems from Microsoft, not really seen since the days of Windows Phone and Windows 8.
