Microsoft will have everyone renting Windows.
They started testing this with Office several years ago and now Office 365 is here. Adobe does the same with their products. As long as you have a license you can download their latest products. There will be no disks in the near future.
I dumped Microsoft a long time ago. My aging computer was a windows 8 laptop. I bought it at a bargain price from a pawn shop. It ran slower than cold molasses running up hill. So I wiped the drive and put Linux mint 18.2 on it. Recently, I upgraded to 18.3. This thing runs like a champ and isn’t overheating my laptop.
I love it!
