Windows 10 Insider Preview Build 17735 & 18214 Releases

2 min read

For Windows 10 Insider testers, this week is a busy week. Two days ago, Microsoft pushed build 17733 to the Fast Ring channel to finalize the resource manager’s “night mode” theme. Now, the company has released the 18214 build to the Skip Ahead channel and upgraded the fast update channel to build 17335. It should be noted that 17335 is the latest preview of Redstone 5, and 18214 is the development branch of the next major update for Windows 10.

Windows 10 build 17735 does not introduce any new features, it is currently in the stage of improving the Redstone 5 bug removal, and there is still one month away from the official release.


The code for Windows 10 build 18214 is 19H1 and is expected to arrive next spring. Although there are currently few new features, they have also introduced some of the features that RS5 testers ushered in last week.


From the changelog, build 18214 ushered in the “Your Phone” application, a safer and faster Internet (Microsoft Edge browser supports HTTP/2 and CUBIC).

A Faster Safer Internet with HTTP/2 and CUBIC
