To register the Windows Phone device to the developer account there is a tool called Windows Phone Developer Registration ( a stand alone tool ) which will be installed by default while installing the Windows Phone SDK ( available in both versions 7.1 and 8.0). As a prerequisite you need to have a valid Microsoft account and a Windows Phone developer account. Each developer account has a limitation to register only 3 devices for application development and if any existing device which is already used with a name it will be reflecting to accept with a new device name. In order to register a phone which is running Windows Phone OS 7.1 we need to use the Zune Software which can be downloaded from the Microsoft website.

Let use see the steps on how to register the device to the Windows Phone developer account, follow the below steps one by one to get this done easily.

Steps to Register:

  1. Connect your Windows Phone device to the Developer machine using a USB cable.
  2. Make sure the phone is switched on and no in lock stage (if locked, then unlock it by sliding).
  3. Open the Windows Phone Developer Registration stand alone tool from the list of programs installed as shown in the screen below. image

  5. Clicking on register again will register the phone successfully and shows the message that the Windows Phone is registered with out any issues as shown in the screen below.
