The only difference is the licensing rules that apply to the use and transferability of the software. The Office 2021 or Office 2019 software and features are exactly the same for all licenses Retail, Volume or OEM. That should be possible depending on how you purchased Office 2021 or Office 2019 either as a retail/ volume license product or included with a new computer (OEM). But what if you want to move Office 2021/2019 software to another computer? Most likely from an old computer to a new replacement machine owned by the same person? Not the ‘one desktop and one laptop computer’ that applied many years ago. ‘Perpetual license’ or non-subscription versions of Microsoft Office 2021 or Office 2019 are limited to just one computer at a time.
Can you move Office 2021 or Office 2019 from one computer to another? The answer is ‘maybe’, it depends on how Microsoft Office 2019 or Office 2021 was purchased.
