Hello,

I bought Office Home and Student 2016 through Amazon (1 user, PC download) in June, 2018 and installed it on my laptop running Windows 7. I recently updated to Windows 10 and wished to reinstall Office. I have the key but, because it is more than 7 years ago, it doesn't appear in my purchase history to download again. Is it legal to reinstall on the same laptop, even though the operating system is different? If so, how may I acquire the software? Thanks a lot for looking at this!

The order history may be incomplete, but you should still be able to reinstall Office via the https://account.microsoft.com/services page. Scroll down to the bottom, past any subscriptions that may have been associated with your account. If Office isn't listed, it may be associated with some other Microsoft account of yours.
