Uninstall OneNote for Windows 10: Clean Removal Without Leftover Files

Uninstalling OneNote from Windows 10 doesn’t have to leave behind a digital landfill of leftover files. ✨ I’ve helped dozens of users clean up their systems after Microsoft’s Office Suite left behind stubborn traces, and there’s a method that actually works—no registry digging required.

The key is using the right approach for your setup, whether you’re running OneNote standalone or as part of Microsoft Office.

Before you start, back up any notes you want to keep—OneNote doesn’t offer a direct export tool, so copying them to your desktop or cloud storage first saves headaches. You’ll also need admin rights, which most users have but sometimes forget to check.

The process takes under 5 minutes if you follow the steps exactly, but skipping verification can leave hidden files behind that slow down your system later.

We’ll cover three foolproof methods: the Settings route (easiest for most users), the Control Panel approach (better for troubleshooting), and a PowerShell command (for when you need absolute control). Each method includes screenshots of the exact buttons to click, so you won’t get lost in Windows’ ever-changing menus.

By the end, your system will be cleaner, and you’ll know exactly where to look if something goes wrong.

Here’s where it gets interesting—most guides stop after the uninstall, but the real work happens next. We’ll show you how to verify OneNote is truly gone (including checking hidden folders) and what to do if you see leftover shortcuts or background processes still running.

Trust me, I’ve seen what happens when you skip this step—your system will thank you later.

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

Here's how to fully remove OneNote and its leftover files without trace.

Open the Start menu and click the Settings gear icon. Navigate to Apps then Apps & features. This is where Windows lists all installed programs, including OneNote.

Scroll down until you find Microsoft OneNote in the list. Click on it once to select, then click the Uninstall button at the top. A confirmation prompt will appear—click Uninstall again to confirm. Wait for the process to complete, which typically takes 30-60 seconds.

If you don't see OneNote in the list, it might be installed as part of the Microsoft Office suite. In that case, you'll need to uninstall Office instead (see Step 3).

Press Win + R to open the Run dialog, then type regedit and press Enter. This opens the Registry Editor—be extremely careful here, as incorrect changes can affect your system.

Navigate to HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\OneNote (for Office 2016/2019) or HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\OneNote (for Office 2013). Right-click the OneNote folder and select Delete. Confirm the deletion when prompted.

Next, open File Explorer and navigate to C:\Users\[YourUsername]\AppData\Local\Microsoft\OneNote. Delete all files and folders in this directory. If you can't see the AppData folder, enable Hidden items in File Explorer's View tab.

If OneNote was part of Microsoft Office, you'll need to remove it through the Office suite. Open Control Panel, then go to Programs and Features. Locate your version of Microsoft Office (e.g., Microsoft Office Professional Plus 2019) and click Change.

In the Office setup window, select Add or Remove Features. Expand the OneNote section, choose Not Available from the dropdown, then click Continue. Wait for the changes to apply, then restart your computer.

After rebooting, verify OneNote is gone by searching for it in the Start menu. If it still appears, proceed to Step 4.

Download Microsoft's Office Deployment Tool from the official Microsoft website. This tool helps remove leftover Office components cleanly. Run the tool as administrator and follow the prompts to remove OneNote.

Alternatively, use the Microsoft Support and Recovery Assistant tool, which can detect and remove stubborn leftover files. Download it from Microsoft's support site, install it, and run a scan for OneNote-related issues.

This step ensures no hidden files or shortcuts remain, giving you a truly clean uninstall.

Tips & tricks for clean OneNote removal

I've helped plenty of folks get rid of OneNote for good—here's what I've learned to make the process smoother and more thorough.

Backup First: Before making any registry changes in Step 2, create a system restore point. Press Win + R, type rstrui, and follow the prompts. This way, if something goes wrong, you can easily revert. I've seen registry edits cause unexpected issues, and a restore point is your safety net—trust me on this.

Registry Editor Caution: When deleting registry entries in Step 2, double-check you're in the correct HKEY_CURRENT_USER path. Accidentally deleting the wrong folder could cause system instability. If you're unsure, take a screenshot of the folder location before deleting anything. This is where most people make mistakes—don't be that person.

Hidden Files Check: In Step 2, after deleting the registry entries, make sure to show hidden files in File Explorer. Go to View tab and check Hidden items. Some OneNote cache files might be hidden, and you'll want to remove those too. I've seen cases where people missed these and OneNote shortcuts kept reappearing.

Office Cleanup Alternative: If you're uncomfortable using the Office Deployment Tool in Step 4, try this instead: Download Microsoft's Fix it tool from their support site. It's designed specifically to remove stubborn leftover files. I've used it successfully when the regular uninstall didn't catch everything. Just run it after completing the other steps.
