When purchasing a Microsoft operating system or Office suite, you will frequently see labels like Retail, OEM, and Volume (MAK/KMS). Choosing the right license type saves money and prevents future activation headaches.
1. Retail License
- Transferability: Can be transferred from an old computer to a brand new PC if you upgrade hardware.
- Target Audience: General consumers, enthusiasts, and small businesses building custom rigs.

2. OEM License (Original Equipment Manufacturer)
- Transferability: Locks permanently to the first motherboard it is activated on. Cannot be transferred to a new PC.
