Update, July 31 (1:30 pm ET): Microsoft released build 19042.423 (KB4568831) to Beta Insiders today, but it's just a re-release of 19042.421 to bring it in line with the Windows 10 May 2020 servicing as of today.
What you need to know
- Microsoft rolled out Windows 10 build 19042.421 to Insiders on the Beta channel today.
- This 20H2 release brings new theme and customization options that first hit the Dev channel earlier this month.
- Included is a new theme-aware Start menu design that looks pretty sleek.
Microsoft launched a new Windows 10 preview build for Beta channel Insiders today, and it brings over several improvements to the Windows Shell that hit the Dev channel earlier this month. Most notably, this update includes a new Start menu design, notifications UI, and more. Today's build comes in at version number 19042.421.
The new Start menu sports an overall cleaner look, giving Live Tiles a unified background that will match your system theme. Notifications also received a bit of a touch up, using the same layout that we've seen with Windows 10X. For new installations, you'll also see a customized task bar layout depending on thing like whether your Android phone is linked to the PC, whether it's a gaming PC, etcetera.
Here's a look at everything that's new in build 19042.421:
Theme-aware tiles in Start
ALT + TAB between apps and sites
Improving pinned sites in Microsoft Edge
A more personalized Taskbar for new users
Improving the notification experience
Making Settings even better
Improving the tablet experience for 2-in-1 devices
Changes, improvements, and fixes

Oh look, Live Tiles! I'm looking forward to these improvements. But I haven't even gotten the "May" 2020 update yet.
Do you have a statement that it is ready, just not available for you yet? I don't even have that. I'm just getting "You are up-to-date."
I do get the thing that says it's coming when my device is ready or whatever.
So I must have something else blocking me. I just installed 1909 this January also manually as Windows Update woukd not deliver it automatically either.
Time to get back into the Insider program. I haven't been bothering lately, because the risk wasn't worth the very little reward, but this is a very nice looking beta build.
A surprise to be sure, but a welcome one. Seems like 20H2 is going to be surprisingly somewhat more substantial than 1909.
So these changes are already part of the Dev Channel release?
They've been there in Dev for some weeks, though some are still A/B tested there.
Yea, Dev channel here. Just got this yesterday along with the beta channel folks. Guess I was B channel.
Looking forward to this one as a non-insider release, especially like the tiles and this one too "We have another new feature we've been working on to make you more efficient when browsing the web: quick access to tabs for your pinned sites. Clicking a pinned site on the Taskbar will now show you all of the open tabs for that site across any of your Microsoft Edge windows, just like you'd expect for any app with multiple open windows."
It’s cool they’re trying to make the design a bit more modern and consistent. I just still wish they’d go back to, or at least include an option to use, the Windows 7 UI, which to me still looks more appealing and modern.
Charms Bar, and the overlay clock.... 😢
Hopefully this means a 100% rollout of the UI changes to the Dev channel in the next build.
What is “new” about it? Other than the colors, it looks exactly the same. Still has the same big, stupid squares around the icons. Painting your house does not give you a new house.
Nor does any update to Windows 10.
Someone has noticed that the new Creative Cloud icons (for example Illustrator, Premiere Pro...) have a white tile instead of a grey one when in dark theme?
I don't see any news
Just got these updates on my Insider Dev machine yesterday. They have been doing so called A/B testing. Some got them some didn't.
That'd be from build 20180 on the dev channel that was released yesterday.
