OEM key is much more cheaper than the Windows 10 product key you bought from Microsoft.

An OEM (Original Equipment Manufacturer) key is a license sold to PC manufacturers (like Dell, HP, Lenovo) to pre-activate Windows on new computers. These keys are:

  • Cheaper than retail licenses (since they’re bought in bulk).
  • Permanently tied to the motherboard (cannot be transferred to another PC).
  • No official Microsoft support (OEMs handle activation issues).

How to Get Cheap Windows 10 OEM Product Key

1. Buy Windows 10 Product Key from Trusted OEM Resellers
OEM keys are meant for system builders, but some authorized sellers offer them separately.

✅ Recommended Stores:

  • Newegg (look for "System Builder" licenses)
  • Amazon (sold by Microsoft or authorized partners)
  • B&H Photo Video
  • Best Buy Business

2. Buy a Refurbished PC with OEM License

Many refurbished business PCs (Dell OptiPlex, HP EliteDesk) come with pre-activated OEM Windows 10 Pro.

3. Find Windows 10 Product Key from an Old PC (If Already Activated)

If your PC originally had Windows 10, the product key is embedded in the BIOS. To retrieve it:
