One of the common requests I've had is how do you know what version of AKU (Adaption Kit Update) you are running.
Well to find out - go into Start... Settings... System then About
From there you should be able to see the Build No of your device.
The Build number is the release number followed by the AKU version.
For example - If it says (Build 14822.214.171.124) it means that I have AKU2.0.0 subsequently if it is 14nnn.1.1.0 it would mean you are on AKU1.1.
