A way to tell if Office was installed in a refurbished computer?

Is there a way to tell if Microsoft Office was installed in a refurbished computer I bought from BestBuy online?

The hard drive been cleaned professionally I believe.
When I had it, there was only one icon on the desktop and no programs in Control Panel.

I bought a refurbished aka used computer from BestBuy.ca, its a HP EliteDesk 800 G1 with an i5-4570 and W7 Pro 64 bit, it has a Q87 motherboard made by HP, its a business motherboard with a few extra business features that come with that chipset, and these computers are used in companies, most likely a major corporation so I would highly guess that it originally had MS Office installed.

Then wouldnt BestBuy just reinstall MS Office and up the price a bit?

Yeah yeah I know all of that.
Any store anywhere sells 365 or 2016, or if I want older and cheaper I can go to ebay, amazon etc.
For 365 - I will NEVER pay for monthly subscription anyways. Thats just dumb for a home user.
You forgot to mention Office online, as an option.

It boils to I am pretty sure this computer had Office installed on it. If the hard drive is original I could somehow retrieve the old over-written data, but I am sure the QueekSquad technical service branch of BestBuy would have had the HD securely wiped. I could spend hours searching and figuring out how to get the old data, maybe spend $100 in software too, when MS Office is only $100cdn anways.

I thought maybe that the MS Office install code would be linked to the operating system somehow.

I have another thought, maybe the Office the corporation had was a retail full version and not an OEM version stuck to the motherboard.

If the computer previously belonged to any organization the hard drive would have been completely wiped to prevent data recovery. There is no way to determine what software was previously on the drive. Not that it matters anyway. If Microsoft Office was previously on the drive the license to use it was not transferred to you.

Edit: A secure wipe of the hard drive is standard practice with almost all organizations when a computer is taken out of service. Either that or physical destruction of the drive but that significantly reduces the resale value of the computer.

Bottom line is that whether or not the computer had Office installed is of zero consequence to you.

Don't forget that they can track you.

Unless you re-installed the original OEM Windows and then MS Office.
It is most probably bundle in as a complete set of Windows and MS Office.

Most do not take such risk as they are reliable for all these.
Hence BestBuy have to get a separate OEM Windows version.
