The blog goes on to explain, "If you recall -- OneCore is the shared core of Windows across PC, tablet, phone, IoT, Hololens and Xbox. It is essentially the heart of Windows. We're doing some code refactoring and other engineering work to make sure OneCore is optimally structured for teams to start checking in new features and improvements in a few months. As a result, these builds may include more bugs and other issues that could be slightly more painful for some people to live with."
In other words, you probably don't want to get this public preview because it might be buggy and won't have any important new features. There's only one item the company highlighted in the blog about the build -- new notifications in File Explorer that tell people about features they might want to try in Windows 10.
So we'll still have to wait a while to see what significant updates Microsoft has planned for Windows 10. When there's anything notable, we'll be sure to let you know.
Becoming an Insider
If you are interested in getting previews of Redstone 2 and Redstone 3, you need to have the Windows 10 Anniversary Update installed and to be a member of Microsoft's Windows Insider Program.
To join, go to the Windows Insider Program page and click "Get Started."
You'll have to agree to opt in. Then go to your computer's Settings / Update & Security / Windows Insider Program and click Get Started. You'll get a warning that the software you're going to download might not be fully tested. If you still want to go ahead, click Next.
Before you can continue, there will be an even more dire warning: "If you ever want to stop receiving Insider Preview builds you may need to remove everything from your PC and reinstall Windows." Click Confirm if you're still interested in testing preview versions. Then restart your computer and go to Settings / Update & Security / Windows Insider Program and you'll see that you're set to get Insider Preview builds.
You're not quite done yet, though -- at least, not if you want to get previews as soon as they're released. Microsoft offers three options for obtaining Windows previews: the Fast ring, the Slow ring and the Release Preview ring.
- In the Fast ring, you get preview builds as soon as Microsoft releases them.
- The Slow ring is the default when you sign up for Windows Insider and it's where you get preview builds after they've gone through some public testing, but before their final release to the general public.
- In the Release Preview ring, you get preview builds only after they've been tested in the Slow ring. This is the least buggy and slowest ring.
