Nice list and it may work, but I must say that #3 is not good sound advice IMO. It is awful risky. One never knows what one is obtaining over the Internet. There could be any number of harmful files in the download. It is safer to either buy it or upgrade via the Store app.

#5 sound a little tricky to giving that most of us only have one key

for number 3. you are right but i mean any valid windows 8.1 pro dvd which you download by the method given and it can be used on many pre installed pc.
5. yes this key is our valid pre installed windows 8 pro key . which can be known by magical jellybean. this is a valid method of upgrade offline not to use internet every time .

there is no need to have another key. because we are activating windows by phone not by internet.
first try this method. it is working.
