may never show up. Had EBay links to some $30-40 priced Home Premium pre SP1 Upgrade versions which can also install as full versions if
1) you wait the 30 days trial and only THEN enter the product key
2) install it, then reinstall it on top of itself.
Amazon had some used copies too for about the same price, but those will say "no operating system" to bypass an amazon policy, but they do come with the disc, or you can contact the seller direct and ask.
I want to know if installing (from disk) Windows Vista on a new computer with pre-installed Windows 10 is possible and, if so, will it function properly?
