A new cumulative update has been quietly released to Windows 10 Insiders on the Slow ring. In an update to a blog post covering a separate Slow ring cumulative update released last week, Insider chief Dona Sarkar has confirmed a new update, KB4034450, started rolling out as of July 5 with a single added fix over the previous release (via MSPU).

New cumulative update quietly issued to the Windows 10 Insider Slow ring

Says Sarkar:

We have released KB4034450 to Windows Insiders in the Slow ring which supersedes KB4022716 and includes a single fix for an issue causing some laptops to boot to a black screen.

These recent cumulative update releases are meant to keep Slow ring Insiders up to date with the latest Creators Update fixes. In the blog post, Sarkar indicates a Fall Creators Update release is planned for the Slow ring "in the coming weeks." When it arrives, however, it will roll out as part of a staggered release meant to simulate the phased process Microsoft uses when a feature update is released to everyone.

If you're on the Slow ring, you should be able to grab this latest cumulative update now through Windows Update.
