Reinstallation of Microsoft Office

[Shamsul1]

Bought the laptop in Nov 2014. Required to carry out recovery a few days back. Windows got re-installed and was subsequently updated to Windows 10 Home Single Language 1903 version when getting online. However, I lost Microsoft Office. I don't have a CD/ DVD or the serial number of the Office with me. Do not remember the Office version that was uploaded. Don't have any Office serial number. However, I have the invoice that reflects the 'laptop' serial number.

I do not want to purchase Office 365 from the Microsoft website again.

How can I reinstall any version of the Office considering it was provided to me as part of the laptop purchase in 2014?

Most likely, at this late date -- you can't!  We have no records of any MS Office product keys associated with individual accounts.  If you did not make a record of the key, there is nothing we can provide you.

IF you bought the PC in 2014, then it was most likely Office 2013 -- and that came in two very different versions.  One used a key stored locally on the PC, but since you reinstalled Windows, that wiped out the key.  The other, known as the Click-to-Run (CTR) version came with a key provided in an email from Microsoft, and that key was not stored locally.  Either way, we have no record of the key to provide you.
