How to use the embedded office license in my laptop using my microsoft account

Question

Hello,

I'm having an issue where the office apps is asking me to sign-in when I have a lifetime access of microsoft office pre-installed to my laptop. I'm suspecting that when I have my student email expired which is logged-in in my office apps the license also got expired and now I can't use my office apps even though I have a lifetime access with my laptop. Please help I'm struggling to fix this issue. Thanks!

Answer 1

Hello, have you already removed your old school account from Windows completely?

Go to Settings, Accounts, Access work or school, and disconnect any old student account listed, then restart your laptop. After that, open Settings, Apps, Installed apps, find Microsoft 365 or Office, select Modify, and run Online Repair. Once done, open Word, sign in with your personal Microsoft account, or skip sign in if prompted and choose Activate Office from File, Account. This refreshes the built in license and forces Office to re-detect the correct activation tied to your device.

Answer 2

The pre-installed “lifetime” Office on a new laptop is normally tied either to:

1. A product key that was redeemed once and then bound to a personal Microsoft account, or
2. A work/school (student) account license that only stays active while the account is valid.

If the Office apps were previously signed in with a student account and that account has now expired, the Office license from that account also stops working. The apps will then start asking to sign in and may show “Unlicensed Product” or similar activation messages.

Use the following steps to recover or confirm the correct license:

1. Sign out of the old (student) account in the Office apps
   • Open Word or Excel.
   • Select the name/profile icon at the top.
   • Choose Sign out from all accounts listed.
2. Sign in with the correct Microsoft account
   • Open Word again and when prompted, sign in with the personal Microsoft account that should own the pre-installed Office (if it was ever redeemed to one).
   • If activation fails or shows “We couldn’t find any Office products,” that account does not have a valid license attached.
3. Check which account actually has the license
   • Go to the Subscriptions page at Subscriptions while signed in with the suspected personal Microsoft account.
   • If the pre-installed Office (for example, Office Home & Student 2019/2021/2024) appears there, use the Install option from that page to reinstall Office on the laptop. This uses the embedded license from that account and does not require a product key again.
4. If Office is still unlicensed after sign-in
   • If the apps still show Unlicensed Product or similar, follow the activation guidance: when Office asks to sign in, always enter the account used to buy or redeem Office. Using any other account will show “We couldn’t find any Office products.”
5. If the only license was the expired student account
   • If the only account that ever had an Office license was the student/work account that has now expired, the license is no longer valid and the pre-installed Office cannot continue to be used under that license. In that case, a new valid license (for example, a retail Office product or a Microsoft 365 subscription) is required and must be associated with a personal Microsoft account, then installed and activated by signing in with that account.

In summary, activation now must be done with the Microsoft account that actually owns the Office license. If that license was only ever provided through the student account, it cannot be recovered once the student account and its subscription are no longer active.
