I've searched through the forum and I think I have most of the answers, however I am a bit confused over product keys.
I have an older 32 bit Vista system which is a candidate for an upgrade to W8 64 bit.
I also have a newer W7 64bit system which I don't want to upgrade
I think that if I take the £24.99 upgrade option then I can download W8 to my W7 64 bit system, save to an ISO file, burn a DVD then use the DVD for a clean install to another system (i.e. format the drive so it is empty then run a W8 install from scratch).
If all this is true, then my one unanswered question is "can I use the product key from the original 32 bit Vista install"?
I can see multiple possible sources of W8 Pro Upgrade, and two
Microsoft Store United Kingdom Online Store - Buy and download Windows 7 Professional, home file sharing, network connectivity, Home Premium
Buy Windows - Microsoft Windows
come in at £24.99 but I'm not sure both are direct from Microsoft.
Which is the better site to use or will either do?
