A family of Microsoft word processing software products for creating web, email, and print documents.
I am currently running Office 2010 Home and Business in Windows 10 simultaneously with Microsoft 365. I only use Outlook in the 365 version and do not have any conflicts.
My Office 97, 2000, 2003, 2007, 2013 all got zapped with my old hard drive and I did not still have installation media and product keys. They all did run previously with 365 on Windows 10, although 97 was a bit flaky.
For Word, I have separate Startup and User Templates folders for each version. They all shared a workgroup templates folder.
Currently, I have Office 2021 Pro on a Windows 11 computer that shares the Startup, UserTemplates, and Workgroup Templates via Dropbox with Microsoft 365.
