The general view is that Windows 7 was Windows Vista with the worst bugs removed. Vista had a bad reputation and has very few users today - less than one percent and significantly less than the earlier XP (
Usage share of operating systems - Wikipedia). OTOH Windows 7 has a good reputation and is still widely used, while Windows 8 went bad again.
Originally posted by Adam You can get Windows 7 licenses for < $20 online, and the upgrade is seamless.
I must admit I did not know that was possible. Have you any links to that and can they be trusted? I'd be surprised if it were from Microsoft themselves as they have thrown everything into getting people to move on from Win 7.
Originally posted by Adam If you switch to Windows 10, that will be the last license you'll have to pay for, since Microsoft is offering feature updates on an ongoing basis.
The expectation is that Win 10 will move onto a rental system, which is what software makers dream of as it gives them a predictable income with relatively little seffort, as they no longer have to produce a spectacular "must have" new version every couple of years, for which they are really running out of ideas. Microsoft already do it with Office 365, as do Adobe with Photoshop, for examples, and it is why Microsoft are so anxious to get people onto Win10 to prepare the ground.
As they are not turning into a charity, and remain firmly against Open Source, the general expectation is that in time Microsoft will require a subsciption for you to get further upgrades, bug fixes and security fixes, or simply be left behind. The situation would not be much different in practice from the old one but with less support (only serious security fixes if at all) for a non-subsribed and hence non-updated copy than before - because the subscription
is for the support. I'll bet it will cost the user more in the long run.
