Sometimes one may feel they need a law degree to interpret EULAs, however, MS does attempt to explain it in layman terms. I suggest that all go to the source > The MS site itself. Here's the best one I've found: Intellectual Property
That pertains to an individual buying one license. If one is performing mass production then I would think it would be a lot cheaper. I would think the more licenses one buys the cheaper it is.
Windows system builder licensing for personal useWindows system builder licensing for personal use Page Overview
If you are building a system for your personal use or installing an additional operating system in a virtual machine, you will need to purchase Windows 8 software or a Microsoft retail version of Windows 8.1 software. Windows 7 and Windows 8.1 system builder software does not permit personal use, and is intended only for preinstallation on customer systems that will be sold to end users.*
In essence that saying that one can personally use and transfer 8 OEM or 8.1 retail version and that one cannot transfer window 7 or 8.1 OEM editions. The matrix on the page explains it better.
However, what got my goat was that they released 8.1 a few months later. My 8 OEM key would not allow me to download the 8.1. ISO. It didn't qualify. I could upgrade to 8.1 via the store, but not fresh install. What a PITA!
We should not confuse store-bought preloaded OEM keys with individually-bought OEM (System Builders) personal-use keys. There is a difference. One may consider buying a System Builders copy. We'll have to see how they lay it out.
It's all good news we know now, instead of the day before
Will the rtm be released as well on July 29 or will it be earlier ?
Well my laptop is Windows 7 but its a slower dual core Toshiba from 2010 and it will qualify for the free upgrade.
I guess my desktop is out of luck then. My desktop I want to keep as an older dual-boot XP/7 gaming machine and older programs but it has a Windows 7 Home Premium OEM key.
Asus M4A78T-E + Phenom II x4 965 CPU. I don't want to upgrade to 10 on this machine. I want to do a newer-ish build for 10. I was thinking a Z97 or Z87 or H97 board (whichever is the best deal) and a low end i5 cpu like i5 4430. But I guess I won't be able to transfer my Windows 7 OEM from the old desktop and install Win 10 on the new one and activate it like that and keep Win 7 on the old one? Not possible right?
I will have to buy my own new retail key?
The only catch is you can't replace your motherboard on that system unless it fails (but there is a debate on that issue).
