Windows 10: How to reuse a microsft office product key after a full computer reset?

I purchased my office product key about 2 years ago when I was building my computer. I had already activated it at the time for my personal use, however, my computer had a major problem a year and a half later and had to be fully reset. Once I got my computer back from the shop, I had lost all access to powerpoint and word via the app. I tried to re-enter my product key but it says that it has been used and could no longer be reused. Can anyone help me with this issue? I would like to use powerpoint again using the same product key.

Windows PC Reset Option Product Key/Office

Assuming you've performed no hardware changes: no, you will not need a product key for Windows 10 to do a remove-everything reset.
When it asks you for a product key upon reinstall, just choose "skip this step", "Do this later",
"I don't have one", or "I'm reinstalling Windows", whatever it offers you.
It should reactivate automatically after you re-establish your internet connection.
Just uninstall your version of Office beforehand (de-activate install from your My Office account page), reset, and when the reset is complete go back to your Office account page and reinstall.
