Use Windows 10 Upgrade Advisor to Upgrade to Windows 10 Mobile from Windows Phone 8.1

Finally, after a REALLY LONG WAIT. Microsoft has started rolling out Windows 10 Mobile to general consumers who have been waiting to upgrade from Windows Phone 8.1, but there is a catch. You will need to use UpgradeAssistant App to check if the upgrade is available on your device.

How to Check if you have an Upgrade?

Download the UpgradeAdvisor App from Microsoft Store

Once installed, it will check if the upgrade is available and how the device can be prepped. The chances are that it will get rid of some temporary files. Once it confirms that the update is available, you will need to check the box which says “Enable Windows 10 Upgrade”.  After this, the device is provisioned for the Windows 10 Mobile upgrade.

Now Go to Settings > Phone Update > Check for Update. Keep pressing if you have all the time in the world. Else let it tell you on its own.

Should You Upgrade?

Million-dollar question. We don’t know because we don’t know if Windows 10 Mobile performs equally smoothly on all devices.

How to skip upgrading from Windows Phone 8.1 to Windows 10 Mobile?

If you are skeptical about the upgrade and want to wait for user feedback for a final go, then here is how to stop your phone from upgrading to Windows 10 Mobile from 8.1

  • Go to Settings > Phone Update.
  • Uncheck The “Automatically download updates” checkbox ticked.
  • This way, you will get a notification about the download, but you won’t download the file unless you want to. Also, an automatic download will not start if connected over Wi-Fi.

Remember, the upgrade will download and sit on your phone. It’s up to you to install it. There is no way to roll back unless you have the ROM saved already.
