OEM vs Retail — Which Key Do You Need?
- Retail: Transferable between PCs. Move your licence to a new machine when you upgrade hardware. Best for users who build or replace PCs regularly.
- OEM: Permanently tied to the first device it activates on. More affordable — the smart choice for new builds, refurbishment, and single-machine permanent installations.
- N editions: EU-compliant versions of Windows without bundled media player software. Functionally identical to standard editions for most users.
