This is not a question, but just an explanation of how I upgraded. I already had Windows 10 on my computer but it was an insider preview that wouldn't update.
I had an old desktop with windows 7 and key, so I hoped to use that to upgrade to windows 10 free. However, when I put that hard drive in my computer, windows would not boot. Startup recovery did not work either.
So I put it back in the old PC and fired it up. I went ahead and started the windows 10 upgrade process. It downloaded and installed, but when it went to do the restart I shut it down.
I figured the unconfigured windows 10 install would work and it did. It took a while for it to get into the windows 10 screen, a really long time in fact. But, it finally went in and windows 10 was set up. However, the key that it upgraded from would no longer work.
In the past, the key did work when upgraded, but I think the machine change had something to do with it. There was a live chat option from Microsoft so I tried that. The rep (likely from India) had to release the key so that it was open to activate.
So long story short, the same Windows 7 key did work for Windows 10. So if you are really on a budget you can still use your Windows 7 system to upgrade to 10 but it's quite a process.
Bonus : That old computer also had office 2010 with a legal key on it, but would not work in the new machine. I used online activation to re-activate the key and it works!
Money spent - Zero!
