Is Buying a Cheap Windows Key Legal in the U.S.?

Many people wonder if buying a Windows key is legal in the U.S., especially when they see prices under $30 online. In this guide, we’ll explain when cheap Windows keys are legal, when they’re not, and how to buy safely.

Why Buying a Windows Key Is Legal in the U.S.

Microsoft offers several types of licenses for Windows, which explains the big price differences:

  • Retail License: bought directly from Microsoft or major retailers. Transferable between PCs and costs around $200+.
  • OEM License: sold to PC manufacturers for new computers—cheaper, but tied to one device.
  • Volume License: used by businesses or schools in bulk. Sometimes unused keys are resold online.

So, the question is buying a Windows key legal in the U.S. often depends on the license type and how the key was obtained.

When It’s Legal — and When It’s Not

In the U.S., it’s legal to buy and resell unused software licenses as long as they were obtained legitimately. It becomes illegal when the keys are:

  • Stolen or generated using cracks or unauthorized tools
  • Region-locked and sold outside the allowed market
  • Used on more devices than the license permits
