"Don't say we didn't warn you…"
"A preview for Windows Phone experts
Windows 10 Mobile Insider Preview is here today, but it’s far from being finished. In fact, it's fairly similar to your current phone (assuming you have Windows Phone 8.1)—just a little rougher around the edges, and with a lot more potential to grow. 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.
Insider Preview vs. Developer Preview
Windows 10 Mobile Insider Preview gives you a sneak peek at Windows 10 for phones. If you’re interested in getting the latest software updates to Windows Phone 8.1, use Developer Preview for Windows Phone 8.1 instead.
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.
