Microsoft is rolling out today the Windows 10 RS5 build 17763 to Windows Insiders in the Slow ring, just two days after it first shipped to Fast Ring Insiders. We've reached that moment where Fast and Slow Ring Insiders are on the same page, and this suggests that the Windows 10 October 2018 update is now almost fully baked.

As you may already know, the preview build 17763 fixed an issue causing battery drain when using certain apps like OneNote, and it also adressed other problems related to Microsoft Edge and Bluetooth audio devices. This build also has known issues affecting the Windows 10 Task Manager, so the Windows Insider team still has some work to do. However, with Microsoft's Ignite conference being just a couple of days away, it's possible that Microsoft will use this opportunity to reveal when the October 2018 will start rolling out worldwide.
We'll see what happens over the coming days, but Insiders on the Release Preview Ring should get ready to receive their first RS5 build pretty soon. The next major Windows 10 update brings several new features including Cloud Clipboard, the Your Phone app and a dark mode for File Explorer, and we'll have more in-depth coverage in the coming weeks.
