Solution 1Recommended

Perform an Online Repair for Microsoft Office

Running an Online Repair replaces corrupted application files and fixes deep-rooted software bugs that standard updates or Safe Mode cannot resolve.

Since the issue persists in Safe Mode and across updates, the core PowerPoint application files handling text formatting are likely corrupted. The Microsoft Office Online Repair tool performs a comprehensive fix by reinstalling clean versions of these files.

1
Open Windows Settings

Click the Windows Start menu and select Settings, then navigate to the Apps section and click on Installed apps or Apps & features.

2
Locate Microsoft Office

Scroll through the list of installed applications until you find your version of Microsoft Office or Microsoft 365.

3
Select the Modify Option

Click on the three dots next to the Microsoft Office application and select Modify from the dropdown menu. If prompted by User Account Control, click Yes.

4
Run Online Repair

In the repair dialog box, select the Online Repair option instead of Quick Repair, then click Repair to begin the process. This may take several minutes and requires an active internet connection.

5
Restart and Test

Once the repair process finishes, restart your computer. Open PowerPoint, select some text, and click the Subscript command to verify it works correctly.

Frequently Asked Questions

Why didn't Safe Mode fix the subscript formatting issue in PowerPoint?

Safe Mode only temporarily disables add-ins, extensions, and customizations. If the bug is caused by corrupted core installation files, Safe Mode will not resolve the issue, and a complete software repair is necessary.

Will running an Online Repair delete my PowerPoint files?

No, running a Microsoft Office Online Repair only replaces missing or corrupted application system files. It does not delete, move, or modify any of your personal presentations or documents.

What is the keyboard shortcut for subscript in PowerPoint?

You can typically apply subscript in PowerPoint by highlighting the text and pressing the Ctrl and Equal sign (=) keys simultaneously.

What is the difference between Quick Repair and Online Repair?

Quick Repair runs offline and attempts to fix minor issues quickly by checking local files. Online Repair takes longer because it connects to Microsoft servers to download and completely replace all software files, making it much more effective for persistent bugs.
