Key Activation

Overview

How to use it? Instructions can be found here.
The key activation option can be used to check whether a key can activate a product without using a confirmation ID.
This option works for Windows Vista / Office 2010 and later versions.
In short, if activation shows failed, it means the key cannot be activated online without a confirmation ID. If activation shows succeeded, it means the key can be activated by simply entering it into the system without relying on a confirmation ID.
This option consumes an activation slot to check.

How does it work?

A SOAP request is sent to Microsoft's SLActivateProduct endpoint at:

https://activation.sls.microsoft.com/SLActivateProduct/SLActivateProduct.asmx?configextension=Retail

The request includes:

The product key
The algorithm type (msft:rm/algorithm/pkey/2005 or msft:rm/algorithm/pkey/2009)
The ActConfigId (obtained from PidGenX during key checking)
PublishLicense.xml
A hardware ID (HWID) binding, randomly generated per request
Client information: system time (local and UTC, taken from the system), locale and geo ID (hardcoded to English/United States), and a randomly generated secure store ID

Microsoft's server responds with either:

An End-User License (EUL) response, meaning activation succeeded.
A SOAP fault containing an HRESULT error code and a message, meaning activation failed.

Since this is a real activation attempt, it consumes an activation slot.

Note: Some Office versions use a different configextension, but Retail appears to work for all products. A single up-to-date PublishLicense.xml also appears to work across all products.

Activation Result	Error Code	Error Message	Meaning
Succeeded			An End-User License (EUL) was received, meaning activation succeeded.
Failed	0xC004C003	103 (Activation) - [PA Product key blocked. ---> Product key blocked]	The key is valid (not generated) but cannot be activated by any means (fully blocked keys, GVLK, etc.).
Failed	0xC004C00D	118 (Activation) - [PA Invalid ActConfigId. ---> Invalid product key unique Id]	The product key type is not supported, for example Visual Studio, PGS:TB keys, Office PIN keys, etc.
Failed	0xC004C004	104 (Activation) - [PA Invalid product key. ---> Invalid product key]	The key is either invalid or has been generated. However, in some rare cases this error is incorrectly returned even when a CID can be generated and the supported product can be activated.
