I was about to buy win7 OEM (newegg special) to install as a Player-Guest in my home laptop. In case you are not aware, windows OEM versions cannot be used on a different motherboard (mobo) whereas the Retail version can be. The OEM versions are always a lot cheaper than the Retail, as Retail includes free msoft CS-help and obviously I don't need that.
It then occurred to me that if I change laptops next year to a Surface 3 (when I can afford it), the win7 OEM may be "keyed" to the mobo on this current laptop and no longer work in a new one.
Does win7 (win8. 8.1) key to the Player or the laptop hardware?
I will need to move the Player Guest .VMDK to another machine at some point.
The Windows 7 OEM System Builder License Agreement requires that the software be installed using the OPK and then resold to a non-related third party, so it's not legal for personal use however if not in the US then consult the EULA for your country.
