Change Office 2016 activation serial number

Used my activation serial one to many times, but now i need to change my invalid activation serial number in Office 2016.
This used to be quite easy by going to program and features and upon selecting Office 2013 and choosing change you could then enter a new serial number. But not anymore, why change everything with a new release?

Now in an elevated command prompt, type this:

cscript "C:\Program Files (x86)\Microsoft Office\Office16\ospp.vbs" /inpkey:XXXX-YYYYY-VVVVV-DDDDD-AAAAA

And now your Office 2016 wants to activate again over the internet, and if the serial is valid you're good to go.
