This error message appears when a form of Windows that is being used is not genuine or has been copied from an original form of Windows. It can also appear when the security certificate for Windows has expired. Users who are getting this message should consider getting a new form of Windows for their computer rather than simply trying to fix the error message.

Users who have tried the command prompt method of fixing the error message and are still not satisfied with the results may have an issue with the registry of their computer. Microsoft recommends that the user of the computer disable the plug and play feature that is available on Windows. Users can also add the registry of their program to the computer and give the proper licensing permission to the program.
