@Smudger - excellent post on the newest (and therefore must be better) MS operating system. Thanks!
This was the same comment that @PeterBJ made.The Hat said:If you upgrade to Win 10 and later then want to reinstall Win7/Win 8 again fresh, you can’t because your key will be useless, it can’t be reused.
There's going to be lots of tears on this new Windows offer, because we love our beautiful old printers..PeterBJ said:"I wonder if doing the upgrade turns the key for your previous OS into a Win 10 key, so it can not be used for a reinstall of your previous OS if you don't like Win 10?"
BE AWARE that it is Microsoft's intention that Windows 10 will be the FINAL operating system ever to be released by Microsoft!
They intend to upgrade it with time as required. I expect it will eventually turn into a subscription-based operating system...
