Live chat
That is the step to talking to someone within a few minutes instead of being on the phone...
Decided to actually chat to them on the app to see what they were like and I had no real issues, I just had to explain what I meant in three different ways to get them to understand lol
But managed to confirm that when I upgrade motherboard I just need to ring the activation line with my 8.1 retail key at hand and they will generate a w10 key. I already knew this based on Glaucus and a few others but wanted to see if I could get the answer from the horses mouth so to speak
15 mins on the chat only - I was armed with EULA section quotes and quotes from members on here stating the path they took to reactivate w10 so they had nowhere to run really.
