Windows 10 Redstone: A guide to the Insider Preview builds
Microsoft never sleeps. Even before the Windows 10 October 2018 Update (version 1809) started to roll out, the company began work on the next major update to Windows 10, due to be released next spring. As it did with the October 2018 Update, Microsoft has been releasing a series of public preview builds to members of Microsoft's Windows Insider Program.
After years of using "Redstone" in its code names, Microsoft is changing it up with the next release, which is code-named "19H1" (for 2019, first half) rather than "Redstone 6." What follows is a list of every preview build of Windows 10 19H1 that has been rolled out to Windows Insiders in the Fast ring, starting with the most recent. For each build, we've included the date of its release, a summary of what’s in the build and a link to Microsoft's announcement about it.
