The Microsoft OneNote desktop application is suddenly missing for multiple users, even though it still appears as installed in Programs and Features.

How to Fix OneNote Desktop App Disappearing in Windows

Product: Microsoft OneNote
Device & OS: Windows
Scenario: Users are attempting to launch Microsoft OneNote from the Start Menu or desktop, but the application and its shortcuts cannot be found.
Observed behavior: The OneNote app shortcuts and search results disappear completely. Reinstalling restores the application temporarily, but the issue recurs, suggesting an underlying shortcut, indexing, or management policy conflict.

Before you start

Verify that you have administrative privileges on your Windows computer, as modifying search index settings or repairing Microsoft Office installations requires admin rights.

Solution 1Recommended

Rebuild Windows Search Index and Recreate the Shortcut

Often, the OneNote executable is still safely on your drive, but a corrupted Windows Search Index prevents it from showing in the Start menu.

Windows relies on an index to quickly display apps in the Start menu. If this index becomes corrupted, applications may seem to disappear. Rebuilding the index forces Windows to scan your program files again.

Access Search Indexer Settings

Navigate to Windows Settings > Search > Searching Windows. Scroll down and click on 'Advanced Search Indexer Settings'.

Rebuild the Index

In the Indexing Options window, click 'Advanced', and then click the 'Rebuild' button under the Troubleshooting section. Allow the process to complete.

Locate the Executable Manually

Open File Explorer and navigate to C:\Program Files\Microsoft Office\root\OfficeXX\ (replace XX with your version, like Office16). Look for ONENOTE.EXE.

Create a New Shortcut

Right-click ONENOTE.EXE, select 'Send to', and choose 'Desktop (create shortcut)'. You can also pin it directly to the Taskbar for easy access.

Rebuild Windows Search Index and Recreate the Shortcut

Index Rebuilding Time: Rebuilding the search index may take some time depending on your hard drive speed and the number of files. Your PC may run slightly slower during this process.

Solution 2

Perform an Online Repair for Microsoft Office

If the executable is missing or other Office applications are also affected, repairing the Office suite will restore deleted program files and shortcuts.

Solution 3

Review Group Policy and Management Scripts

In enterprise or managed IT environments, automated scripts or Group Policy Objects (GPOs) may be inadvertently deleting app shortcuts from user profiles.

Frequently Asked Questions

Why does OneNote show in the Control Panel but not in my Start Menu?

This commonly occurs when the application shortcuts are accidentally deleted, hidden by an IT Group Policy, or when the Windows Search index becomes corrupted and fails to display installed applications properly.

Where is the default installation path for the OneNote executable?

The default executable file (ONENOTE.EXE) is typically located at C:\Program Files\Microsoft Office\root\OfficeXX\ (where XX represents your installed Office version, such as 16 for Office 2016, 2019, or Microsoft 365).

Will repairing Microsoft Office delete my OneNote notebooks?

No. Repairing Microsoft Office only fixes the application program files, shortcuts, and registry entries. Your OneNote notebooks are stored safely in the cloud via OneDrive or in your local Documents folder.

Can antivirus software cause OneNote to disappear?

Yes, occasionally an overly aggressive antivirus or endpoint protection program might falsely flag an application shortcut or executable and move it to quarantine, causing the app to disappear from your interface.
