My copy went through a lot of phases. It started life as a retail copy of Windows 8 Pro (disc) which I bought along with a Lenovo laptop around 2012 (Ivy Bridge was still fresh). It was then upgraded to 8.1 and 10 at launch date. The laptop died around 2016 (split in half). When I built this PC I transplanted the laptop's HDD into the PC and weirdly enough, it works. No license problem whatsoever (I believe I asked about this here years ago). That copy had been cloned to different SSDs, went through several upgrades and whatnot. It's on Windows 11 now. But, in essence, it's still the same copy that hailed from that Windows 8 disc.
I have another PC upstairs that runs Windows 10. That one.... let's just say I followed the cough Tech Yes City way, if you catch my meaning.
