Yesterday I showed you how to repair Microsoft Office in Windows 10. If Office suddenly starts acting quirky, this is a great first step towards troubleshooting. It’s a lot easier than uninstalling and reinstalling Office. Today, I’ll show you how to do it in Windows 7. If you need the Windows 10 instructions, click here.
First, search for Change or remove a program in the search box, then click on the result.
Scroll down until you find Office 365 in the list of programs.
Click the Change tab at the top.
You’ll be given the choice between a Quick Repair or an Online Repair. The online repair takes longer, but it can fix all of your issues. I’d suggest starting with the quick version to see if it helps. Just click Repair to get started.
