How to Set Default Apps by File Type in Windows 10 & 11 (MP3, PDF & More)
Tired of double-clicking a file and having it open in the wrong app? This guide shows you exactly how to take control of which program opens which file type in Windows 10 and 11 — plus what to check when a default won't stick because of policy controls.
🛠️ What you'll do:
• Open Default Apps in Settings
• Find and select an app to configure
• Set the default app for .mp3 files
• Browse defaults by file type
• Set the default app for .pdf files
• Check for policy controls that can block changes
• Inspect an app's current file associations
• Run a system-file repair (SFC + DISM) if defaults keep resetting on their own
