Before you install Windows 10 Mobile Insider Preview


A preview for Windows Phone experts

Windows 10 Mobile Insider Preview is here today, and we’re already working on the next version to bring you more great features. Join the Windows Insider Program to make sure you get all the new features that are on the way. If you’re okay with a moving target and don’t want to miss out on the latest stuff, keep reading. Insider Preview could be just your thing.

Download and install the preview only if you

  • Aren't installing it on your primary phone. If you have a backup phone, that's a perfect candidate for Insider Preview.

  • Want to try out software that’s still in development and like sharing your opinion about it.

  • Don’t mind lots of updates or a UI design that might change significantly over time.

  • Really know your way around Windows Phone and feel comfortable troubleshooting problems, backing up data, or restoring your original operating system if something goes wrong.

We're not kidding about the expert thing. So if you think APN is a cable news network, Insider Preview may not be right for you.

Things to keep in mind

Unexpected phone crashes could damage or even delete your files, so you should back up everything. Some hardware—like Bluetooth speakers—might not work, and some apps might not install or work correctly. You might also have trouble connecting to home or corporate networks.
