This service applies Retail/OEM keys inside a virtual machine to obtain the error code, so you may lose activation attempts if the result is "Online Key". Use this tool at your own risk!
Please do not mass-scan keys, or check many invalid or very old keys — otherwise your account will be automatically blocked. The service only supports Windows 7 / Office 2010 keys and newer.
