Image Product Keys and Activation (Standard 7 SP1)
7/8/2014
Windows Embedded Standard 7 product keys are used to:
- Determine the grace or evaluation period of an image.
- Generate a product identifier (PID) to identify each unique installation of Standard 7.
Standard 7 uses a new type of activation called "Embedded Activation" that provides automatic activation when a valid Volume License Runtime key is used during image creation. Images created without a product key or with a 180-day Evaluation License key will expire at the end of their trial period and cannot be activated or upgraded.

Out of Grace Behavior
If an image has exceeded its trial period, it is considered "out of grace" and the following behaviors will be exhibited:
- The device will restart every twenty minutes without warning.
- The Standard 7 logo will be appended with "Evaluation Copy."
- The device desktop background will be black.
- A message will appear on the device desktop background stating "This copy of Windows is not Genuine".
- Messages are written to the log file located at %windir%\debug\wlms.log that read "The grace period has expired and the system has no license. This computer will shutdown."
Note
The Standard 7 setup process performs several verifications, which rely on the target device's date and time settings. For optimal performance, confirm that the target device is set to the correct date and time.
Evaluation Images Cannot be Upgraded
Standard 7 does not support in-place upgrades from one license type to another. It is recommended that you verify the product key type used in your image or answer file before you use it in production. Images and answer files must be re-created to upgrade the license. You cannot upgrade an image by changing the product key.
How to Determine Your Image's License Details
When your image is created, messages are written to the log file located at %windir%\Panther\UnattendGC\setupact.log that state what type of product key is in use for that image. This log can be reviewed after image creation to determine your image's license details.
You can also use the Windows Software Licensing Management Tool (SLMgr.vbs) to obtain details of the license in use for your device. Enter the following command at an elevated command prompt on the device to obtain the device's current license information:
Slmgr -dli
The information returned will include last five characters of the product key used for the device's image as well as the license status and the length of time until the license expires.
