Look, I've been poking around this site for a bit now- not to mention about the web in general- and, I'm sure that somewhere, there might actually be a straight-forward answer to this (no doubt here-but, again, I couldn't seem to find it)- so, please forgive me for what is probably (yet another) - dumb question, but, can someone please tell me, in plain English exactly what my rights are concerning this software? To be more precise: When my family purchased the full OS of XP, we knew and understood that we were given the right to place this OS onto up to 3 computers (so long as they belonged to us). FURTHERMORE, once we had upgraded to Vista, we were allowed the right to pass this software on to someone else... In other words, it went with the disk- so long as no more than 3 computers were registered with that particular OS-disk, and all three of those rightfully belong to the person in question then, it was our understanding that everything was legal- fair use and all of that.... This does NOT seem to be the case with Windows 7. It fact, with Windows 7 all we seem to keep finding is more and more confusion concerning our rights and fair usage... Look, we've NEVER pirated- nor would we want to, but the simple fact of the matter is that we are all completely and utterly in the dark here. And, we just want a couple of questions answered. Because there are two people in our household- we have purchased 2 Full Windows 7 Home Premiums on the understanding that things now go with the individual and not the hardware with that purchase.(Upgrades and OEM versions go with the Motherboard-understood)- but here's the question: Let's say that I'm an amateur/homebrew IT person (just trying to keep his computer and mine running), and, let's suppose that as such, I'm going to make mistakes- many of which may indeed require me to employ the "final solution" (ie- wipe the drive and re-install), let us also- for just a moment imagine that some of the various pieces and parts of said home-built machines might actually be replaced over the years..... Does Windows 7 actually limit the number of times that registration of said system when it's the same one? Does it go by the person or the system, and if it's the system, which part is it? And, if it's the person, 1) what in the hell am I supposed to do here? How many times may I actually install this OS into my system (I'm not kidding, is it really only a limited amount- even after paying for what YOU called an "unlimited OS"?) If I upgrade something in my system, how many problems can I expect due to your DRM? SERIOUSLY!!!! Are you really going to expect another $300 every time my husband opens up some malware-laden POS e-mail from his mother? Seriously.... Don't try to shunt me off onto the EULA (Defeats the purpose of the question- since it seems that what I want is an actual translation thereof!) Point is? What Can I do with this Windows 7 Full OS, and what can't I do?
