production key

Question

where do you get production key to unlock microsoft word document?

Answer 1

Sorry, if a particular document is password-protected, there is no way to circumvent that password.

On the other hand, if you are saying that you need to activate your Office installation, you usually do that by signing in to your associated Microsoft account.

If you don't have a Microsoft Office product (perpetual license or subscription), you will have to get one first.
