You can view your OS version in Settings>System>About.

To revert back to Windows Phone 8.1, folllow these steps:

1. Download and install the latest version of the Windows Device Recovery Tool to your PC.
2. Launch the recovery tool and connect your phone using a USB cable. If your handset isn't detected, click My phone was not detected to force the application to rescan for and detect the phone.
3. In the next screen, click your phone, wait a few seconds, and you'll see your phone information and the software available for download to roll back to a previous operating system. To continue, click Reinstall software.
4. Next, the recovery tool will warn you to backup all your data, settings, and apps before continuing, as the rolling back process will delete all the previous data in your phone. Click Continue to proceed.
5. Now, the recovery tool will download the image from Microsoft's servers and replace Windows 10 Mobile that is currently on your phone. The process will take some time depending on your internet connection and the hardware in question.
