Perform an Online Repair for Microsoft Office

Running Microsoft Office's built-in repair tool can fix corrupted application files causing the Undo/Redo sequence to fail.

Windows includes a built-in feature to repair Microsoft Office installations. This process replaces missing or corrupted application files that may be causing PowerPoint to glitch and lose track of the undo/redo history.

Open Windows Settings

Right-click the Start button on your Windows taskbar and select 'Apps and Features' (or 'Installed apps' if you are using Windows 11).

Locate Microsoft Office

Scroll through the list of installed applications or use the search bar to find your specific version of Microsoft Office or Microsoft 365.

Modify the Installation

Click on Microsoft Office and select 'Modify' (in Windows 11, click the three-dot menu icon first and choose Modify). Grant administrator permissions when prompted by User Account Control.

Run Online Repair

Select the 'Online Repair' option for a comprehensive fix, then click 'Repair'. Follow the on-screen instructions to complete the process. Once finished, restart your computer and test PowerPoint again.

Quick Repair Alternative: You can try selecting 'Quick Repair' first, as it takes less time and does not require an internet connection. If the issue persists, proceed with the 'Online Repair' option.

Frequently Asked Questions

What is the keyboard shortcut for Redo in PowerPoint?

The default keyboard shortcut to Redo an action in Microsoft PowerPoint is Ctrl + Y. You can also click the curved forward arrow in the Quick Access Toolbar at the top of the window.

Why is the Redo button grayed out in PowerPoint?

The Redo button normally becomes grayed out if you have not used the Undo command first, or if you made a new edit immediately after undoing an action, which permanently clears the redo history for that step.

Does Online Repair reinstall Microsoft Office entirely?

Yes, the Online Repair option essentially downloads and replaces the Office application files to fix deep-seated corruption issues, which is why it requires a stable internet connection to complete.

Will repairing Office delete my PowerPoint presentation files?

No, repairing Microsoft Office only replaces software application files and resets registry keys. Your personal documents, presentations, templates, and saved files will remain perfectly safe and unaffected.
