How to uninstall Microsoft Office Product Key

This post will help you to uninstall Microsoft Office Product Key. When you purchase MS Office, you get an activation key with a length of 25 characters to use Office products (like Word, Excel, PowerPoint, etc.) with all the features and without interruption. If, for some reason (like changing the product key or re-installing the same key), you need to remove the Microsoft Office product key, then you can do this easily using the built-in option available in Windows OS. This post has covered all the steps.

You can also simply uninstall Microsoft Office and then re-install Office to enter a new product key. But, if the same task can be done by uninstalling only the product key, then it is better than removing the entire Office product.

Uninstall Microsoft Office product key

You can uninstall the Microsoft Office product key using Command Prompt, as follows:

1. Open elevated Command Prompt window
2. Execute command to access Office path
3. Run command to view the last 5 characters of Office product key
4. Execute command to uninstall Office product key.

First of all, open elevated CMD or Command Prompt.

Access the Microsoft Office folder in Command Prompt window. For that, you need to execute a command that will include the path of the MS Office folder where it is installed. For example, if a 64-bit version of Microsoft Office 2016 is installed in C Drive, then the command would be:

cd C: > Program Files > Microsoft Office > Office16

You have to check where and which version of MS Office is installed and then execute the command accordingly.

Now run the command to check the last 5 characters of the installed product key of Microsoft Office. The command is:

cscript ospp.vbs /dstatus

You can see the license status (activated or not) and the last five characters of the MS Office key. Copy those characters.

This is the final command for uninstalling the current product key. The command is:

cscript ospp.vbs /unpkey:ABCDEX

Replace ABCDE with the last 5 characters of the MS Office key and execute the command. It will uninstall the Office key. When you open Word or other Office apps, it will prompt you to enter a product key.
