Frequently Asked Questions

Why did my Excel files suddenly turn into blank white icons?

This happens when Windows loses the file association for .xlsx files. It is typically caused by a corrupted Microsoft Office installation, an interrupted Windows update, or missing registry keys related to the Excel application.

Will repairing Microsoft Office delete my saved Excel files?

No. Running an Online Repair or standard repair through Windows Settings only fixes the application program files and registry entries. Your personal documents and spreadsheets are completely safe and will remain untouched.

What is the difference between Quick Repair and Online Repair?

Quick Repair runs much faster and attempts to fix issues by replacing corrupted files using local data already on your computer. Online Repair takes longer because it completely uninstalls and redownloads Office from Microsoft servers to fix more severe issues, which requires an active internet connection.
