Good news, Windows Phoners! A new Windows 10 preview build is just a couple of days away.

Microsoft’s Gabe Aul announced today that the next Windows 10 for phones preview build is slated to begin rolling out Friday, April 10, at 10:00 am PT/1:00 pm ET. In order to get the update, you’ll need to be a Windows Insider and have the Windows Insider app on your compatible smartphone. The current list of Windows 10-compatible phones includes the Lumia 630, Lumia 635, Lumia 636, Lumia 638, Lumia 730, and Lumia 830.

We’ll have to wait until Friday before we know for sure exactly what’s inside the next Windows 10 for phones preview build. However, Microsoft teased last month that many more phones are expected to be included in the next Windows 10 preview build, including major phones like the Lumia 920, Lumia 1020, and Lumia 1520. That’ll greatly expand the number of users that’ll get to try Windows 10 on their smartphone for the first time. Exciting!
