Windows OEM Versions

Introduction

• Windows OEM stands for Original Equipment Manufacturer.
• Not an edition of Windows but a type of license for Windows.
• Common editions include Pro, Home, etc.

Differences Between OEM and Retail Licenses

1. Support:

   • Common belief: OEM versions don't get Microsoft support, but this isn't entirely true.
   • Reality: Both OEM and retail can get support, with some nuances.

2. Intended Consumers:

   • OEM License: Generally bought by system builders or manufacturers to install on prebuilt machines.
   • Retail License: Sold directly to consumers, e.g., in retail boxes.

3. Packaging:

   • OEM: Basic sleeve, meant for bulk.
   • Retail: Full packaging, like a box.

4. Pricing:

   • OEM versions are usually cheaper.
   • Example Pricing from Newegg:
     • Windows 11 Home: Retail ~$139, OEM ~$120-$130
     • Windows 11 Pro: Retail ~$200, OEM ~$160-$170

5. Installation:

   • OEM might come with manufacturer-specific bloatware if bought pre-installed on a device.
   • Direct OEM purchase (clean install) has the same content as a retail version.

6. Transferability:

   • Retail: Easier to transfer license to another computer, typically after wiping the old one.
   • OEM: License tied to the machine's hardware, especially the motherboard.

Checking Your License

• Use the command: slmgr /dli in command prompt.
• Displays the edition and type of license (OEM or Retail).

Support Nuances

• Whether it's retail or OEM, both get some level of Microsoft support.
• Microsoft's Binding Agreement:
  • Pre-installed Software: Contact manufacturer first but Microsoft may provide limited support.
  • Retail Purchase: Microsoft provides limited support directly.
• Installation documentation locations:
  • System32 directory: license.rtf
  • System32/licenses: Comparing files, no differences in licenses texts between default, OEM, and others.

Practical Implications & Myths

• Microsoft Support:
  • No strong evidence OEM versions are denied support by Microsoft.
  • More intense legal language around manufacturers providing support but no explicit denial from Microsoft.
• Purchasing OEM for Self-builds:
  • OEM licenses can be bought for self-built systems, similar to manufacturers.
  • Ensures a lower upfront cost for Windows licenses.

Conclusion

• OEM vs. Retail: Real Differences
  • Pricing and Transferability are real practical differences.
  • Support differences are overstated and not fully accurate.
• Final Thoughts:
  • OEM is a cost-effective choice for many but with slightly more restrictions.
  • Questions from the audience and personal experiences were invited for discussion.
