Here are the steps for changing it using windows,
- Before you proceed, make sure that all Office Applications are closed.
- Open cmd and Run it as an Administrator.
- Locate the location of the ospp.vbs
- Normal location is C:\Program Files (x86)\Microsoft Office\Office16 (can be seen on the picture) if they have a 32-bit Office installed.
- Location for 64-bit Office is normally under C:\Program Files\Microsoft Office\Office16.
- Once location has been determined, run the following command on cmd.
- Type in cd (path location).
- Once they are already on the correct path, just run cscript ospp.vbs /dstatus
- On the first image of cmd, you can see that it showed an installed product key “WB222”.
- Do take note that there are instances that more than 1 product key is installed so you need to check all the result and take down all the product keys.
- Once you have all the product key, you can now proceed on running the second command.
- Type in cscript ospp.vbs /unpkey: (Last 5 of installed product key) and hit Enter.
- On the second image of cmd, you can see that product key was successfully uninstalled.
- If they have multiple product keys installed, you need to remove all of them.
- After product key is removed, open up Control Panel – Credential Manager – Windows Credential.
- Remove all credentials that has “Microsoft Office”.
After doing the previous steps, you need to back-track and make sure that everything is clean.
- On the cmd, try running the dstatus again to verify that no installed product keys are being detected seen on the first image.
- Under Work/School Account, make sure no account is connected (troubleshooting will be different if it is connected to AD as we need to bypass it instead of disconnecting).
- Re-open Credential Manager and verify that everything is clean.
You can now proceed on re-activating Office by opening any Office Application.
Go to File – Account – Sign In.
Login the account that has the license.
Office should now activate properly.
