Re: Not just a service pack
I would argue the more relevant point is not what changes were made between versions, but how they are licensed. You either own Windows XP, 7 or 8. The difference between 8 and 8.1 does not exist, it's simply an update to software using the same license. From a technical point of view it may be interesting to argue about exactly how big the differences between 8 and 8.1 are, but from the perspective of tracking who owns which OS, which is all these trackers are looking at, there is no difference between them at all.
