Hi,
An OEM version is permanently tied to the first system it is activated on
and is not transferable to a different system. This is a well-established
limitation of the OEM license, and one reason why it is cheaper than a
retail version. While you can make some upgrades or replacements to the
system, major changes are not allowed, nor can you remove it from the system
entirely and then install and activate it on another system. An OEM license
lives and dies on the system it is first activated on.
