To fix MS Word asking for a product key on your student account, you need to sign in using your official university email as a "Work or School account" and verify that your university plan includes desktop applications.

Hello @MOHAMAD SHAHJHA,

Good day! I hope you are doing well.

To help provide the most accurate and effective solution, could you please share a bit more information about your setup?

• As the question is under the Education tag, are you using your official university/school email account to sign in to Microsoft Word? If yes, is it also connected to your Windows device?
• When signing in, are you selecting Work or School account or Personal account?
• Are you experiencing this issue only in Microsoft Word, or do other Office applications (such as Excel or PowerPoint) also prompt for a product key?
• What exact error message do you see when Word requests a product key? A screenshot (with your personal information removed) would be helpful if possible.
• Have you recently installed or reinstalled Microsoft Office?
• Have you tried signing out of Office and signing back in using your school account?
• Are you able to access Microsoft 365 services through your university account at office.com?

This additional information will help us better understand your environment and any troubleshooting steps already performed, allowing us to provide guidance that is tailored to your situation.

I look forward to your response and will be happy to assist you further in getting this issue resolved.

Kind regards,
