I upgraded on 31.7.2015 from a valid fully up-to-date windows 7 home OS.
I changed the country code to US like I was advised when I kept getting the upgrade errors - by the way Microsoft Australia was no help at all, they had no idea what to do. They just said wait a while a try again.

All was working great until yesterday when for some unknown reason my registration for Microsoft office was lost. I fixed this but then straight after it came up with the water mark saying Active Windows.

I followed the instructions but it said unable to activate and gave error code OxC004f074 - saying I have no KMS installed. Looking up online there are several fixes for this but they all require the full key. I do not have this yet since I upgraded and only have the 20 digit temporary code. I am very confused as to what to do next. I am loath to call Microsoft Australia again for fear or getting even more frustrated and getting help.

Thank you in advance for your time.
