How to Fix OneDrive Prompts to Choose an App at Windows Startup

Product: Microsoft OneDrive
Device & OS: Windows
Scenario: Starting up the Windows computer with Microsoft OneDrive enabled.
Observed behavior: At every startup, Windows displays a dialog asking which application should open an item, indicating it cannot associate a startup file or link referenced by OneDrive with a default program.

Before you start

Before modifying your startup configurations, look closely at the "Pick an app" dialog box to identify the exact filename or file extension it is referencing, as this will help you determine which application is missing.

Solution 1Recommended

Identify the File and Set the Default Application

Use this solution to manually assign the correct application to the unassociated file type that is triggering the startup prompt.

Windows shows the "Pick an app" prompt when a file is set to open at startup, but there is no default program assigned to handle its specific format. Setting the correct default app resolves the loop.

Identify the file format

Check the startup prompt to see the name and extension of the file Windows is trying to open (e.g., .txt, .pdf, or .docx).

Open Windows Settings

Press the Windows key + I to open Settings, then navigate to "Apps" and select "Default apps" from the left sidebar.

Choose default apps by file type

Scroll down the Default apps page and click the link labeled "Choose default apps by file type".

Assign the application

Locate the file extension noted in step 1, click on the current default program (or the plus icon if none is assigned), and select the appropriate application from the list.

Identify the File and Set the Default Application

Pro Tip: If the referenced file is an Office document, ensure you have a compatible office suite installed and set as the default to prevent this error from recurring.

Solution 2

Perform a Windows Clean Boot

A clean boot helps isolate third-party software conflicts that might be causing the OneDrive startup prompt.

Solution 3

Test with a New Windows User Profile

Create a new local user account to determine if the issue is tied to corruption within your current Windows user profile.

Frequently Asked Questions

Why does Windows ask me to pick an app every time I start my computer?

This happens when a file, shortcut, or background process is configured to run automatically at startup, but Windows does not have a default application assigned to open that specific file format.

How do I reset all default file associations in Windows?

You can reset all file associations back to Microsoft's recommended defaults by going to Settings > Apps > Default apps, scrolling to the bottom of the page, and clicking the "Reset" button under "Reset to the Microsoft recommended defaults".

Does reinstalling OneDrive fix startup errors?

If the error is caused by a corrupted OneDrive installation trying to launch an unknown configuration file, reinstalling OneDrive can resolve the issue. First, unlink your account, uninstall OneDrive from the Control Panel, and then download the latest version from Microsoft's website.
