Microsoft is planning to detail its “next generation of Windows” at an event later this month. The software giant has started sending invites to media for a Windows event on June 24th. Both Microsoft CEO Satya Nadella and chief product officer Panos Panay will be presenting at the Windows event. Microsoft’s Windows event will start at 11AM ET / 8AM PT on June 24th.

The invite comes just a week after Nadella teased a “next generation of Windows” announcement. Microsoft is expected to detail its next significant changes to Windows, and they will likely include a number of visual enhancements. We’re expecting to see some significant UI changes to Windows under something codenamed “Sun Valley.”

Microsoft confirmed last month that Windows 10X, its OS originally built for dual-screen devices, will no longer ship. The company is now rolling the visual elements of Windows 10X into the main version of Windows 10 instead.

A lot of the visual work has already started, with new system icons, File Explorer improvements, and the end of Windows 95-era icons. Microsoft is also focusing on improving the basic foundations of Windows, with fixes for a rearranging apps issue on multiple monitors, the addition of the Xbox Auto HDR feature, and improvements to Bluetooth audio support.

Nadella has also promised to unlock a better economy for developers and creators within Windows itself, so we’ll likely get a closer look at the store changes coming to Windows. Microsoft has been working on a new app store for Windows in recent months, and rumors have suggested Microsoft will open its store up to all apps and rival payment platforms.

The Verge will be covering Microsoft’s Windows event on June 24th, so stay tuned for all the latest news.
