How to Install Windows Phone 8.1 Preview for Developers

Microsoft had announced Windows Phone 8.1 to the world last week at the BUILD conference. They also announced that a Preview for Developers Program will available  in April similar to the one they rolled out when GDR3 was launched last year. Event though it is called ‘Preview for Developers’ any Windows Phone 8 user can get by following the simple instructions in this email. The program will allow you to install the 8.1 update early on any Windows Phone 8 device and get updates before the carriers and also before Nokia releases their Nokia Cyan update.


How to Install Windows Phone 8.1?

As we said before this is a developers preview which means you need to have a developer account. Unless you are a real developer, you might not be interested in signing up the Microsoft Developer site by paying a $19 fees. But for a normal user, you can still get a free developer account. Here is how to do it.

  1. Sign up for Microsoft’s App Studio: which is free of cost, using your Microsoft ID which is used on your phone and allow them to register your email address. Once you have the confirmation on the account created, now you need to install an app on your phone.
  2. Install the Preview for Developers app and then sign in with the same ID which you used to create the App studio account in step 1.
  3. Now you can see an option “Enable Preview for Developers”, check the option and click done.
  4. That’s it. You are now enrolled to the developers program. Now when the update is released, Go to Settings-> Phone Updates and click check for updates button and you will be able to see the updates.

Nirmal is a big fan of Windows phone ever since it was released. He started off with Nokia Lumia 800 and then got the Lumia 920. Presently he owns the Lumia 730 and Lumia 930.


  1. I’ve installed WP 8.1 OS on my 720… Now mobile performance is really worst..
    It takes much time to get photos loaded.. There r many drawbacks.. Many apps r not opening at all..
    Battery life has been dropped drastically.

    Now how can I improve my lumia performance ?? :(

  2. “RE: It will not damage your phone or cause any issues.”

    Refer to Section 7.c. at

    I am not entirely convinced that waiving off support for the phone is a healthy choice for the regular mortal user.

  3. If apps are the issue, then the migration is not proper. What you can do is to install any new keyboard or language pack from the settings. This will force an update which will rectify the app issue. Well, regarding battery performance, check the new Battery app and moreover this is a preview and we cant complain much as this is not a forced update.

  4. Well, cant blame them. Some operator which have phones in contract have this issue of warranty and support. But this will go off once you install the final version.

  5. This will run on all Windows Phone 8 devices, but be warned that this is a preview build and you might see issues. So if you are ok with it, you can install.
