So I just found out that MS has obliterated the Pro licence that I paid for about a year ago. I did a clean install as per usual (done dozens prior) and always ended up on Pro, but this most recent time ended up on Home for the first time ever. Naturally, something was off. I logged into MS Accounts management where, about 6 months ago I was still able to see my actual licence purchase within my account billing / order history. Now, my licence purchase has been wiped from history entirely. That is the world of "digital" licences, apparently. What can someone do to resolve this? The licence was tied to my HWID, but clearly that is not the case anymore. And wiped from billing history. I am quite frustrated now and skeptical now about modern day Microsoft and Windows 10 when something that you pay real money for can simply be taken from you with no traces left behind. Thank you for your time and any suggestions.
