OEM is the method system builders use to attach their product key directly to the motherboard's on-board memory. The full version lets you reuse the product key across multiple computers, which will simply disable the previous binding on their KMS servers when you enter it. That’s a bit confusing, I hope!
The available versions encompass the complete package. Each variant has its own SKU, with retail and OEM options differing in features. The retail SKU supports installation for both 64 and 32-bit systems, while the OEM version typically comes with one of them. Microsoft representatives have clarified that using a 64-bit OEM key for a 32-bit installation is acceptable in some cases and not others. The OEM keys are intended for system builders, meaning technical support and retail materials aren’t included. Retail packaging previously contained product manuals during XP, 2000 and to some extent 7. When audited by Microsoft, businesses receive a cap of five retail licenses, unlike OEM which has different restrictions. Some Win 8 Pro keys can be upgraded to Win 7 Pro or Vista Business, but retail versions generally don’t support such changes.
