When buying a Windows license online, one of the most common questions is: should you choose an OEM or a Retail license?
Both types are legal and widely used, but they are designed for different needs. Understanding the difference helps you choose the right license and avoid unnecessary costs.
🔹 What Is a Windows OEM License?
An OEM (Original Equipment Manufacturer) license is typically installed on a PC when it is first built.
OEM licenses:
• Are activated on a single device
• Cannot be transferred to another PC
• Offer lifetime activation on the original hardware
• Are commonly used by system builders and businesses
OEM licenses are fully genuine and activate directly through Microsoft servers.
🔹 What Is a Windows Retail License?
A Retail license is designed for individual users who want flexibility.
Retail licenses:
• Can be transferred to another PC
• Are ideal for personal users
• Offer lifetime activation
• Receive full Microsoft updates
Retail licenses are generally more expensive because of their flexibility.
