Windows Embedded Standard 7 can be licensed with different SKUs, each of which allows and prohibits certain features from being used on your embedded device. SKU Compliance Packages are a new feature that'll be available in WES7 Service Pack 1 to help ensure that devices are in compliance with the terms of their chosen licensing agreement. They're currently available in the CTP.
Here's how they work: In the WES7 SP1 Distribution Share, which can be seen in Image Configuration Editor or Image Builder Wizard, you'll see a new folder under FeaturePacks called SKU Compliance. The folder contains a package for each of the currently available SKUs -- WS7C, WS7E, and WS7P. Once you've chosen a SKU, perhaps by using the License Assessment Tool (LAT), you can add its respective SKU CP to your Answer File. Using the licensing frameworks built into Windows, the package will ensure that functionality not permitted under the terms of your SKU is disabled in the image.
"The way each feature behaves depends on how the feature was implemented. For e.g., Snipping Tool executable will be present on the device but will do nothing when launched. Windows Media Center will show a dialog box indicating that it isn't permitted on the SKU. In most cases, it works on a feature level -- that means, for e.g., that SKU CP can disable DirectAccess even if networking packages are installed."
The documentation provided with CTP contains more info about how each feature behaves with SKU CP, but be sure to test your device scenarios to confirm they work as expected. SKU CP are designed to be a tool to help you comply with your license, but they don't replace testing your device scenarios or the terms of your licensing agreement.
