Did you follow the links? Obviously not. And yes, I did follow other links
about Windows 7 in the footer area, and even did some searching via their search box and they did turn up some downloads for extras and the like. They also found some pages that no longer link in to anything else, as if they're old ones that are no longer valid.
Are you suggesting Microsoft are NOT showing everything for sale in their Store in the proper Store pages?
Anyway, average users will follow the basic front door access, which is what I did, and MS do not have Win 7 for sale any more.
BTW My son has an old link for a free three month trial version of Win 7 Enterprise that still takes you direct to the page which has no other links to it or from it.
