Yesterday, Microsoft released a brand new Windows 10 PC Insider Preview build for Insiders in the Fast and Skip Ahead rings that included several notable improvements. However, one such change was not listed in the official changelog: an updated look for the Microsoft Messaging app.

It appears that the built-in Microsoft Messaging app has received a Fluent Design makeover with Acrylic blur and Reveal effects. This is the first significant update to the Microsoft Messaging app since Microsoft pulled Skype integration from it back in 2016. Before you ask, it doesn't look like this update is rolling out on Windows 10 Mobile, at least not currently.

For those unaware, the Microsoft Messaging app in Windows 10 on PC is used to show SMS conversations that are synced from a Windows phone, as well as carrier-specific SMS messages on Windows 10 PCs with cellular connectivity. The app cannot be used to send SMS text messages on PC, however.

Perhaps these improvements are also in preparation for Microsoft's upcoming Andromeda device, which I talked about back in 2017 being a dual-screened, foldable tablet with telephony capabilities. That device will be able to make calls and texts, and as such will use the Microsoft Messaging and Phone apps.

Regardless, the new improvements to the Microsoft Messaging app are a welcome addition, and one that continues to align the rest of the inbox Windows 10 apps with Microsoft's new Fluent Design System.

Thanks for the tip, @falmnd!
