This is described as an upgrade version. All the descriptions and all the reviews don't clarify this.
If you install the upgrade version, you must, must install into an existing hard drive with existing operating system.
That said, this is my experience.I changed 3 computers to win 7. Two went well with existing hard drive, xp and vista, and activated.
Actually, I had formatted the hard drive with xp, but somehow the installation continued from the system recovery path.
One computer, however, I got a new solid state drive and installed this version.
It would not activate, saying the product key was not genuine.
I guess the hard drive change triggered MS's genuine product verifier.I did a lot of research before the upgrade, but apparently, not enough.
In this case, being a layman with some knowledge did not help.
I knew what OEM or builder's version meant, at least, and because this version is "fulfilled by amazon", I paid about $40 more than the cheapest offering.
I assumed I was set to install anyway I wanted. Amazon, despite its policy not to refund an opened software, said it would give me a full refund, if Microsoft did not help me.Microsoft helped me!
My past experience with MS not withstanding, the technician from MS checked the validity of the product key and took over my computer to make the product keys valid.
I am guessing that MS is willing to support the software where the software is genuine (and paid for).
By the way, this version does have genuine product key for 3 installations, if that was not clear.
I don't know if MS will do this for low cost builder or OEM version.Call me a fool, but I am going to change another hdd to ssd - the vista computer which has win 7 now.
Samsung ssd comes with software disk for such a move which I already used once, very easy experience. I don't expect any trouble, since OS is activated as genuine.I hope this review was clear enough.
I certainly went through some confusion.
I would recommend changing to win 7 now, at least if you are still on xp. Go to Microsoft website for help with upgrading to win 7. I am avoiding win 8, especially as I don't want to use an operating system built for mobile phones.I would recommend Amazon to be very clear about its description of this product.
I would recommend Amazon to be prepared for the flood of customer calls when xp support does end and people start panicking.3 stars is for my troubles and to get people's attention.
The product itself works and is supported.
The Amazon was helpful and supportive.
The seller, I think, must also change the description to avoid confusion.
