Windows Embedded CE System Components
A regular question we still get asked, “What Microsoft Windows Embedded CE License do we require?”
Well presently in Windows Embedded CE 6.0 R3 there are 4 variants. These being Core, Core Plus, CID (C6G) and Professional.
Obviously which one you need to purchase will depend on the components included as part of the Platform Builder Workspace. The list of what is included in each variant can be found on the Microsoft web page:-
You can find the information on the Microsoft Embedded web here.
Then to check the image you’ve built is what you think you’ll need to use the VS2005 Platform Builder built in tool. To use the Run-Time License Assessment Tool
1. From the Tools menu, select Platform Builder for CE 6.0, and then select Run-time License Assessment Tool.
2. To continue, view the Terms of Use for the Run-Time License Assessment Tool and then click Accept. Otherwise, click Decline to close the dialog box and cancel the operation.
3. In the Run-time License Assessment Tool dialog box, in the Current CE Run-Time Image field, click Open and then navigate to the directory where the run-time image file that you want to license is located.
4. To save the report in HTML format for future reference, from the File menu, select Save Report.
Hope this is of help.

Very good experience share!
