If you purchased a product key and it’s not activating via the normal methods, there is a real possibility you were sold an invalid license.

Telephone activation should not be needed for Windows 10 anymore. See Microsoft’s Windows 10 Activation page. PLEASE NOTE: The instructions below are out of date and no longer appear to be working. Please exercise caution and due diligence when selecting a vendor for OEM Windows licenses. In our experience, an OEM license should ALWAYS include a physical copy of the software vendors who are selling electronic product keys only (with no media) should be treated with extreme caution to avoid fraud. Provided you can agree to and accept Microsoft’s OEM license terms, you can purchase an OEM license for Windows 10 at a reasonable discount from the full retail version.
