Windows 10: Is MSDN product key illegal?

Hello,Is MSDN product key which came with a workstation illegal? There are many workstations at office that came with Windows product key and it works normal. I have been told that you can't use it in a production environment at office, you need to buy a new product key for your Windows 10. Is it true?

I need to know about MSDN code. I bought an MSDN Key for Windows 10 Pro, what will be differences if I had bought Retail License?

Will I have the license if I need to Re-Install Windows when I had activated the Windows using MSDN Product Key??

Product keys from MSDN subscriptions should not be sold separately.

About MSDN or TechNet Product Keys

They are genuine Microsoft product keys, they are actually retail licenses, but it is intended for a particular product channel either the Microsoft Software Developer Network (MSDN) or TechNet for IT Professionals who pay a subscription fee.
The main purpose is for evaluation purposes. The great thing about them, unlike trial Microsoft software, MSDN or TechNet keys don't expire. Because the agreement under which the subscription is provided is a single license, none of the software should be
distributed outside of it. Even though its $50,000 worth of licenses, it is for one person only to use and no one else. Unfortunately, regardless of the licensing terms, persons still abuse the program, either giveaway product keys or resell it on auction
sites. Microsoft licenses it in good faith that customers won't do so, but I guess human nature wins out.

In your case, what probably happened is, you bought an MSDN licensed key, which carries up to 10 activations unlike full packaged retail licenses which only carry 1 activation. The person who sold it to you probably sold it to 10 other persons.
Somewhere along the way, one of those persons might have installed it on a second system, activated it, because it went past 10 activation threshold, Microsoft detected it that it was being abused and blocked the key from further use.
