I personally would get some form of EA agreement with Microsoft so you can avoid this situation, however, this may not be an option for your shop.
Are you just referring to OS licensing or OS and application?
How are you using OSD? Image, Sysprep/minisetup, etc...?
If you use sysprep, you can also simply not include the activation key (it would then prompt you for entering the license key).
Other than that - "what zman said" pretty much. Bit more description of what you're trying to do, and life could be made easier with the right agreement with Microsoft, but down to your budgets + so on.
What's in the realm of the possible for you?

Since we dont have a volume licenses, we are not using sysprep option, we are taking the images as per the machine model.
If i use sysprep will the issue be reolved, if yes then can you provide me the steps as how to proceed with this option.
