What does OEM mean?
OEM product keys are priced lower than their retail counterparts, but use the same software as retail versions of Windows.
Per Microsoft's EULA regarding OEM, the product key is tied to the PC motherboard which it's initially installed on, and there is typically no transferring the key between PCs afterwards. On versions of Windows which require a valid product key for media download from Microsoft (like Windows 7), OEM keys will be rejected.
Can I directly upgrade from an older operating system?
No, you cannot. A clean installation is required.
What is a clean installation?
A clean installation means formatting your hard drive before installing Windows, so make sure that you have backed up your files.
