The difference between OEM (Original Equipment Manufacturer) and Retail versions of Windows lies mainly in the terms of use, cost, transferability, and support. Here’s a detailed comparison of the two versions:
1. Cost:
- OEM Version: The OEM version of Windows is generally cheaper than the Retail version. This is because the OEM version is intended to be sold to computer manufacturers or system builders for pre-installation on new computers or devices.
- Retail Version: The Retail version is more expensive because it’s sold directly to consumers and includes additional benefits such as support and transferability.
2. License Type and Transferability:
- OEM Version:
- An OEM license is typically tied to the first computer it is activated on. This means that once you install Windows using an OEM key, the license cannot be transferred to another device.
- If the computer’s hardware (especially the motherboard) is replaced, the OEM license will most likely be invalid, and you’ll need to purchase a new license.
- Retail Version:
- A Retail license is more flexible. It is not tied to specific hardware (aside from the product key activation), meaning it can be transferred to a new device, as long as it’s only installed on one device at a time.
- You can uninstall it from the old computer and reinstall it on a new one. This is ideal if you upgrade your computer or need to replace its components.
3. Support:
- OEM Version:
- OEM licenses come with limited support. You will typically need to rely on the manufacturer of the computer (or system builder) for technical support and warranty issues related to Windows.
- If you encounter issues, the OEM vendor is responsible for assisting you.
- Retail Version:
- Retail licenses come with direct support from Microsoft. You can contact Microsoft Support for help with activation, troubleshooting, and other technical issues.
4. Installation Media:
- OEM Version:
- The OEM version often comes without installation media (like a DVD or USB drive). Instead, it’s usually pre-installed on a device or delivered with a recovery disk or a download link for installing the operating system.
- Retail Version:
- The Retail version typically comes with full installation media, either a DVD or USB stick, that can be used to install Windows on your device. You’ll also receive a product key, which you’ll need to activate Windows after installation.
5. Update and Activation:
- OEM Version:
- The OEM version is activated by default when installed on a compatible system. However, if you make significant hardware changes, particularly to the motherboard, you may face issues with re-activation, as the license is tied to the original hardware.
- Retail Version:
- Retail versions allow for easier reactivation and can be moved from one system to another, as long as it’s uninstalled from the previous system. Microsoft’s activation process is more flexible for retail licenses.
6. Warranty:
- OEM Version:
- The OEM version does not have any additional warranty or support from Microsoft. If the OS encounters problems, you’ll need to rely on the seller or the manufacturer for help.
- Retail Version:
- With a Retail version, you get the Microsoft warranty, which may include customer service and support options directly from Microsoft if you encounter any problems with the operating system.
Summary of Differences:
| Feature | OEM Version | Retail Version |
|---|---|---|
| Cost | Cheaper | More expensive |
| Transferability | Tied to one computer, cannot be transferred | Can be transferred to another device |
| Support | Limited support from the manufacturer | Full support from Microsoft |
| Installation Media | Often comes without physical media | Comes with DVD or USB installation media |
| Updates/Activation | Tied to original hardware, may require reactivation | Flexible, can be reinstalled or moved |
| Warranty | No warranty from Microsoft | Microsoft warranty included |
Which One Should You Choose?
- Choose the OEM version if:
- You are building a new computer or buying a pre-built system and you don’t need to transfer the license to another device in the future.
- You’re looking for a more affordable option, and you don’t mind relying on the manufacturer for support.
- Choose the Retail version if:
- You want the flexibility to transfer the license to another device in the future (especially if you upgrade your computer).
- You want direct support from Microsoft in case of any issues with your operating system.
- You want installation media for backup or future use.
