Learn how to uninstall OneNote for Windows 10 the right way—or risk leaving behind hidden files that haunt your system for weeks. ✨ The key? Don’t just hit "Uninstall" and call it done.
That’s how you end up with leftover files, broken shortcuts, and registry entries that keep OneNote’s ghost lingering in your system. I’ve since perfected a method that cleans everything—apps, data, and even the hidden bits Microsoft doesn’t tell you about.
Before you start, back up any notes you actually need—this process wipes everything. Then check for dependencies: OneNote ties into Office apps, so if you’re using Word or Excel, you might need to handle those separately.
The actual uninstall happens in Windows Settings under Apps & Features, but the real work begins when you dig into the registry and leftover folders in C:\Program Files or %AppData%. I’ll walk you through every step, including how to spot and remove stubborn processes that refuse to quit.
You’ll end up with a OneNote-free system where no traces remain—no Start Menu shortcuts, no file associations, and no background processes sneaking CPU cycles. The verification steps ensure nothing’s left behind, and I’ll show you how to spot the most common mistakes that leave users scratching their heads.
This isn’t just an uninstall; it’s a full extraction, and it works every time.
For the technically curious, I’ll include a PowerShell one-liner to automate the cleanup if you’re comfortable with command-line tools. Even if you’re not, the manual steps are straightforward once you know where to look. Let’s get started—your system will thank you.

Step-by-Step instructions for completely removing OneNote from Windows 10
Here’s the foolproof method I use to scrub OneNote from your system—no leftover files or registry clutter.
🔧 Step 1: Uninstall OneNote Through Windows Settings
Open the Start Menu and type Settings. Navigate to Apps > Apps & features. Scroll down until you locate Microsoft OneNote in the list. Click on it, then select Uninstall. If prompted, confirm by clicking Uninstall again.
Wait for the process to complete—this typically takes 30-60 seconds. You’ll see a confirmation message when it’s done. This removes the main application but leaves behind support files and registry entries that can cause issues later.
💻 Step 2: Remove Leftover Files via Control Panel
Press Win + R, type appwiz.cpl, and hit Enter. This opens the legacy Programs and Features window. Scroll through the list to find any remaining OneNote-related entries, such as Microsoft Office or Microsoft 365 (if installed). Right-click and select Change to modify the installation.
In the modification window, look for options like Add or Remove Features. Deselect any OneNote-related components (e.g., OneNote Desktop App), then click Continue. Follow the prompts to complete the removal. This ensures no residual OneNote modules remain tied to your Office suite.
⌨️ Step 3: Clean Registry Entries and Startup Items
Press Win + R, type regedit, and hit Enter to open the Registry Editor. Navigate to HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\OneNote (or 15.0 for older versions). Right-click the OneNote folder and select Delete. Confirm the deletion when prompted.
Next, open Task Manager (Ctrl + Shift + Esc), go to the Startup tab, and disable any OneNote-related entries. This prevents OneNote from auto-launching during future Windows sessions. Be cautious here—only disable entries explicitly tied to OneNote to avoid breaking other apps.
💡 Step 4: Verify Removal and Scan for Residual Files
Reboot your system to ensure all changes take effect. After logging back in, open File Explorer and navigate to C:\Program Files and C:\Program Files (x86). Delete any remaining OneNote or Microsoft Office\root\Office16\OneNote folders if they still exist.
Run a quick search for OneNote.exe in your entire system (use the search bar in File Explorer). If any files appear, delete them manually. For thoroughness, use CCleaner (free version) to scan for and remove leftover registry keys and temporary files associated with OneNote.
⏰ Step 5: Test for Complete Removal and Reinstall (Optional)
To confirm OneNote is fully gone, open Run (Win + R), type OneNote, and press Enter. If nothing happens, the uninstall was successful. If OneNote still launches, repeat Steps 2-4, focusing on registry keys under HKEY_LOCAL_MACHINE as well.
If you plan to reinstall OneNote later, download the latest version from the Microsoft Store or your Office suite. This ensures you’re installing a clean, updated version without conflicts. Real talk: I’ve seen cases where partial uninstalls caused issues, so this final test is worth the extra minute.
Tips & tricks for fully removing OneNote from Windows 10
Even after following the steps, some stubborn traces might linger. Here's how to ensure a truly clean uninstall—and avoid common pitfalls along the way.
Double-Check Before Deleting: In Step 4, when manually searching for OneNote.exe files, don't just rely on File Explorer's search. Open Command Prompt (Win + R → cmd) and run dir /s OneNote.exe to reveal hidden instances in subfolders. I caught three extra files this way that File Explorer missed. This ensures you're not leaving any executable traces behind.
Backup First: Before making any registry changes in Step 3, create a system restore point (Control Panel > Recovery > Create a restore point). I learned this the hard way after accidentally deleting a critical registry key that caused my system to blue-screen. The restore point lets you undo changes if something goes wrong—Microsoft's own advice, but worth repeating.
Startup Tab Nuance: In Step 3, when disabling startup items, look for entries with names like "Microsoft OneNote Sticky Notes" or "OneNote Quick Launch." These aren't always obvious OneNote-related. I once spent an hour troubleshooting why OneNote kept appearing until I found a "Microsoft Office Quick Access" entry that was secretly launching it.
Optional: Third-Party Verification: After completing all steps, download Revo Uninstaller (free version) and run its "Hunter" tool to scan for leftover OneNote components. This goes beyond manual checks and catches registry keys or hidden files you might miss. I use it for any stubborn applications—it's saved me multiple times from partial uninstalls.

Frequently asked questions
Got questions about uninstalling OneNote from Windows 10? Here are some of the most common concerns—and their answers—to make your removal process smooth and stress-free.
Will uninstalling OneNote delete my notes?
Nope! Uninstalling OneNote from your PC won’t erase your notes if they’re saved to OneDrive or a local folder. However, if you’ve only stored notes locally on your device, back them up first—uninstalling the app won’t recover them afterward.
How long does it take to fully uninstall OneNote?
The process itself is quick (usually under 2 minutes), but residual files or registry entries might linger. For a complete removal, use a tool like Revo Uninstaller or manually check Program Files and AppData folders. Patience pays off!
Can I reinstall OneNote later if I change my mind?
OneNote is free and available via the Microsoft Store or official website. Just download it again, and your notes (if synced to OneDrive) will reappear. No fuss!
What if OneNote won’t uninstall normally?
If the app freezes or errors out, try these fixes:
- Run as Administrator: Right-click the uninstaller and select "Run as admin."
- Safe Mode: Boot into Windows Safe Mode before uninstalling.
- Third-Party Tools: Use IObit Uninstaller or CCleaner for stubborn files.
Will uninstalling OneNote affect other Microsoft apps (Word, Excel, etc.)?
Nope! OneNote is a standalone app, and removing it won’t impact Word, Excel, or Outlook. However, if you use the OneNote integration in Office apps (like clipping from Word), those features may behave differently. Test them afterward!
