Windows 10 Technical Preview update for Windows Phone is now available!

Just as Microsoft has promised, the update for Windows 10 Technical Preview for phones is now ready to be downloaded. Okay, so they are an hour plus late due to server issues, but we can confirm that the update is NOW LIVE. At least for SOME phones (our Lumia 635, for example, is getting the update).

Users who are part of the Windows Insider program can now head to their device Setting > Phone Update and check for a new OS update. Make sure your phone is charged up and preferably you are on Wi-Fi to download the bits (the update is 450 MB).

Not familiar with the Windows 10 Technical Preview and how to enroll or what to do? Just read our how-to article to get started, or our big page with all the important links about this update.

The list of changes in Build 10051 is quite long, including Project Spartan, new Mail and People apps, and more! Read the full changes here.

We will follow this post with details about the update, some hands-on videos, and numerous other articles about the update, so stay tuned.

Note: _If you are REGISTERING a phone for the Insider program, you may still have an error doing so. Microsoft is aware of the issue and trying to fix. For users already on Build 9941 (old build) you can just go to Settings and hit Phone Update > Check for Updates.

In the meantime, you can jump into our Windows 10 forums if you are having problems or want to see what other people are sharing!

Happy downloading!
