Microsoft recently warned that Slow Ring Insiders would soon receive their first Windows 10 20H1 build, and the company finally delivered today. If you’re on the Slow Ring, you can now download the build 19013.1122, which isn't the latest 20H1 build that Microsoft released for Fast Ring Insiders last week (that's the build 19018), but pretty close.
Until today, Slow Ring Insiders have been testing the Windows 10 November 2019 Update (19H2), along with Insiders on the Release Preview Ring. Microsoft has yet to say when the November 2019 Update will be released, but the public rollout may begin as soon as tomorrow, which happens to be this month’s Patch Tuesday.
According to a previous report, the 20H1 update may reach RTM status as soon as next month, though Microsoft may continue to test it with Windows Insiders for a couple of months before it’s becomes generally available. Compared to the November 2019 Update, which is a minor release, 20H1 brings several new features including a new Cortana Beta app that will be updated through the Microsoft Store, a new Cloud download option for reinstalling Windows 10, improvements to Bluetooth pairing, and more.
