What does Microsoft Office 2010 OEM installation mean

I have tried it and it works.

Just download the trial version corresponding to the version you have, and when it asks you to enter the product key enter your key and it will complete the full install process.

https://www.microsoft.com/oem/en/products/office/pages/office_2010_starter.aspx explains the answer, in short, "no".

How Is Office Starter 2010 Offered?

Office Starter 2010 is not a trial–it has a perpetual license that does not expire. Office Starter 2010 is an advertising-supported base productivity suite that is available only on new PCs. It must be preloaded on new PCs at the point of manufacture. Office Starter 2010 is not available for existing PCs at any time after manufacture; for example, Office Starter 2010 cannot be installed on new PCs being sold by resellers, even brand-new PCs. It will not be sold through distribution or available to end users as a standalone product.

To learn more about how to purchase and distribute Office Starter 2010 licenses, visit the worldwide OPC Office 2010 Licensing page.
