Retail, OEM, Volume and MAK: what you are actually buying

If you have browsed software keys anywhere, you have seen tags in the product name: [Retail Online], [BIND], [MAK:Volume], OEM. They look like inventory codes. They are not. They describe the licence type, and that decides what you are allowed to do with the key for the rest of its life.

Getting this wrong is the single most common reason a cheap key turns into a wasted purchase.

Retail

A retail licence is the one most people picture. It is sold to an individual, and it is transferable — you can deactivate it on one machine and activate it on another. If your motherboard dies, a retail key generally survives the repair.

Retail is the most flexible option, and it is priced accordingly.

OEM

OEM licences are sold to be pre-installed on hardware. The critical property: an OEM licence is permanently tied to the first machine it activates on. Specifically, it binds to the motherboard. Replace that board and the licence is, in Microsoft's terms, finished.

OEM is cheaper for exactly this reason. If you build or upgrade PCs often, the saving is usually not worth it.

Volume and MAK

Volume licensing is designed for organisations. A MAK (Multiple Activation Key) is a single key with a fixed number of activations attached — you might see 100PC or 1000PC in a listing. Each activation consumes one of the pool.

Two things people misread here:

• The activation count is a pool, not a per-device licence you can resell individually. Splitting a volume key across unrelated customers is outside the terms of the volume programme.
• Volume keys are issued to a named organisation. That matters if you ever need support directly from the vendor.

BIND

A [BIND] tag means the licence binds to the account or device it is first activated against and cannot be moved afterwards. Treat it like OEM: fine for a machine you intend to keep, poor value if you expect to migrate.

The practical rule

Before you buy, ask one question: will this licence ever need to move?

• Moving to a new PC later, or expecting hardware repairs → Retail.
• Single machine, keeping it for years, want the lowest price → OEM or BIND.
• Multiple machines under one organisation → Volume/MAK, sized to the pool you actually need.

If a listing does not say which type it is, that is worth asking about before you pay — not after.
