Can I replace Office 365 with Office 2019?

Can I replace my existing Office 365 with Office 2019 on my computer using Windows 10? If so, how do I do it?


You may certainly switch from Office 365 to Office 2019.

You will need to uninstall Office 365 from Control Panel > Programs and Features, then install Office 2019.

However, don't expect your Office 365 serial key to work for activating Office 2019. A separate serial key must be bought for Office 2019.
