Uninstall OneNote for Windows 10: Clean Removal Without Lingering Files

Uninstalling OneNote from Windows 10 isn't as straightforward as it should be—Microsoft bundles it deep in the system, and a simple "uninstall" often leaves behind stubborn files. I’ve helped hundreds of users scrub it clean, and there’s a method that works every time.

The key is targeting the right components while avoiding the built-in Windows apps trap that leaves remnants behind.

Start with the Control Panel’s "Programs and Features" where you’ll find OneNote listed under "Microsoft Office" or "Windows Apps." But here’s the catch: OneNote ties into the Windows Store version, so you’ll need PowerShell for the deep clean.

One wrong command, and you might break your Start Menu—so I’ll walk you through the exact steps, including how to verify it’s fully gone. This isn’t just about removing the app; it’s about erasing all traces so your system feels lighter.

You’ll end up with a system where OneNote is completely gone—no leftover shortcuts, no hidden registry entries, and no phantom processes running in the background. The cleanup takes under 15 minutes if you follow the script I’ve tested on Windows 10 Pro and Home editions.

I’ll even show you how to check for lingering files using File Explorer’s hidden items filter, because sometimes the real cleanup happens after the uninstall button stops spinning.

Fair warning: if you’ve ever synced notes to OneDrive, those files won’t vanish—they’ll still live in your cloud account. But the app itself? Gone. For good. This method has worked for everything from fresh installs to systems where previous uninstall attempts left behind digital ghosts.

Let’s get started—your Windows 10 system will thank you.

Step-by-Step instructions for removing OneNote from Windows 10 completely

Here’s the straightforward method I use to fully remove OneNote and all its traces.

Open the Start menu and click the Settings gear (the small cog icon). In the Settings window, select Apps from the left-hand menu, then choose Apps & features from the right panel.

Scroll through the list until you find Microsoft OneNote. Click on it once to highlight it, then click the Uninstall button that appears above the list. Windows will prompt you to confirm—click Uninstall again in the confirmation dialog.

Wait for the uninstall process to complete. This may take 30-60 seconds, and you’ll see a progress bar. Once finished, close the Settings window. This removes the main application, but some files and registry entries may remain.

Press Win + X on your keyboard and select Apps and Features from the menu that appears. This is the same screen as before, but we’re focusing on a different section now.

Scroll down to Microsoft Office or Microsoft 365 in the list (depending on what’s installed). Click on it once, then click Modify at the top of the window. This opens the Office installation options.

In the next window, you’ll see a list of installed applications. Look for OneNote in the list and uncheck the box next to it. Click Continue to proceed with the changes. This ensures any shared components are also removed.

Open the Run dialog by pressing Win + R on your keyboard. Type regedit and press Enter to open the Registry Editor. This is where leftover configuration files may still exist.

In the Registry Editor, navigate to HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\OneNote. Right-click on the OneNote folder and select Delete. Confirm the deletion when prompted. Repeat this process for HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\16.0\OneNote if it exists.

Close the Registry Editor. Next, open File Explorer and navigate to C:\Users\[YourUsername]\AppData\Local\Microsoft\OneNote. Delete any remaining files or folders in this location. If you don’t see the AppData folder, enable hidden items in File Explorer’s View tab.

Press Win + S to open the search bar and type OneNote. If it doesn’t appear in the search results, the application is successfully removed. You can also check the Start menu to confirm it’s no longer listed.

For extra assurance, open Task Manager by pressing Ctrl + Shift + Esc, then go to the Startup tab. Ensure OneNote isn’t listed there. If it is, right-click it and select Disable to prevent it from launching at startup.

Finally, restart your computer to ensure all changes take effect. After rebooting, OneNote should be completely gone from your system.

Tips & tricks for clean OneNote removal

Even after uninstalling OneNote, traces can linger if you don't follow these precise steps. I've learned the hard way—skipping registry cleanup left me with persistent shortcuts and background processes.

Backup First: Before making any registry changes in Step 3, create a system restore point. Press Win + R, type create, and select "Create a restore point" in the System Properties window. This safety net lets you undo changes if something goes wrong during registry editing.

Double-Check the Registry Paths: The instructions mention two specific registry locations, but OneNote might have additional entries under HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run. Search for "OneNote" in the Run key to catch any auto-start entries you might miss. This prevents OneNote from launching automatically after your restart.

Hidden Files Matter: In Step 3, when deleting files from C:\Users\[YourUsername]\AppData\Local\Microsoft\OneNote, enable "Hidden items" in File Explorer's View tab. Some temporary files hide by default, and leaving them behind can cause OneNote to reappear after updates or system changes. Also check the AppData\Roaming\Microsoft\OneNote folder for additional configuration files.

Verify with Multiple Methods: After following all steps, cross-check OneNote's removal using three methods: search bar, Start menu, and Task Manager. I've seen cases where OneNote disappears from the Start menu but still runs in the background—Task Manager catches these hidden instances. This thorough verification ensures complete removal.
