We get a lot of questions about Microsoft Office and Windows 10. A reader asks: “I run Windows 7 and Office 2007. When I update to Windows 10, will my Office have to be reinstalled? Thank you for your help and interesting and useful letters to the years.”
Updating to Windows 10 shouldn’t affect programs already installed on your PC (with the exception of things that are part of the Windows 7 operating system like Media Center and the built-in Games pack.)
Programs and files are left undisturbed by the upgrade (some folks have had issues, but the vast majority have not). The only problem you might see if that an older program might not be compatible with Windows 10.
In this case, Microsoft says Office 2007 and forward will be compatible with Windows 10. I’d still make sure that all of my important files are backed up before doing the upgrade. They should all be backed up anyway, but if they aren’t, this is a good time to do it.
