I can only rely on my experience. I ordered the chair Feb 8, 2021, delivered April 9, 2021. They reply fast when I email them. And they did not charge my account until it shipped.
I got mine from Madison seating for $570 ... took 2 months to deliver though
Supposed to be refurbished ... but looks new, not even a small scratch anywhere
I have a custome built PC ... I installed win8 on a fresh SSD drive ... only key it asked was the product key for Win8.
I think if you run the upgrade ... it will ask for a previous version key (like all winOS upgrade). But if you run a new install it won't.
Thanks for this. Burned it to a DVD and did a clean install. I had problems during activation, but a call to MS support fixed it real quick, I was surprised I got a live operator 2 minutes on the call ...
