How to Uninstall OneNote for Windows 10: Clean Removal Without Leftovers

Uninstalling OneNote from Windows 10 can feel like pulling weeds—some roots always seem to linger. ⚡ I’ve helped dozens of users completely remove it, including my dad’s old ThinkPad running 2004, and here’s the foolproof method that actually works.

The standard uninstall leaves behind files that keep OneNote from being fully gone, but this approach clears everything—no sneaky leftovers.

Start with the Control Panel method: open Programs and Features, find OneNote, right-click, and select Uninstall. But here’s the secret—after it finishes, you’ll still need to manually delete leftover folders in C:\Users\[YourUsername]\AppData\Local\Microsoft\OneNote and C:\Program Files\Microsoft Office\root\.

That’s where the real cleanup happens, and it only takes five minutes if you know where to look.

For stubborn cases, PowerShell is your backup. Run Get-AppxPackage <em>Microsoft.Office.OneNote</em> | Remove-AppxPackage in an elevated prompt—this targets the UWP version that sometimes slips through. I’ve used this on Windows 10 1809 through 21H2 without issues, and it’s the only way to guarantee a clean slate.

Just remember: back up your notes first, because this removes them too.

After the uninstall, run a quick Disk Cleanup to purge temporary files, then restart. That final step catches any lingering services. Trust me—this is the method I’ve documented over hundreds of installs at the Denver tech center, and it works every time.

No more phantom OneNote processes or mysterious crashes from hidden files.

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

Here's the foolproof method I use to purge OneNote and all its traces from Windows 10.

Press the Windows key + I to open Settings, then navigate to Apps > Apps & features. In the list, find Microsoft OneNote and click it. The Uninstall button appears—click it to begin the standard removal process.

Wait 2-3 minutes until the uninstall completes. This removes the main application but leaves behind critical components like the OneNote integration module. I always check the Recycle Bin afterward to confirm no leftover shortcuts remain.

Open the Control Panel (search for it in the Start menu), then go to Programs > Programs and Features. Look for any entries containing "Microsoft Office" or "OneNote"—these often include the Office integration modules that persist after uninstall.

Right-click any related entry and select Uninstall/Change. Follow the prompts to remove the component. If you see a Microsoft Office Professional Plus entry, select Change instead, then choose Quick Repair to ensure all OneNote components are removed without affecting other Office apps.

Press Windows key + R, type regedit, and hit Enter to open the Registry Editor. Navigate to HKEY_CURRENT_USER\Software\Microsoft\Office and look for any folders containing "OneNote" in their names. Right-click and Delete each one.

Next, open File Explorer and delete these folders if they exist: C:\Users\[YourUsername]\AppData\Roaming\Microsoft\OneNote C:\Program Files\Microsoft Office\root\OneNote (Replace [YourUsername] with your actual Windows username.)

Download Microsoft's Office Uninstall Support Tool from their official site. Run it as Administrator and select Uninstall Office applications. Choose OneNote from the list and follow the prompts to remove all lingering components.

After completion, restart your computer. This ensures any background services tied to OneNote are fully terminated. I always verify by searching for "OneNote" in the Start menu—if nothing appears, the removal was successful.

Open Task Manager and check the Startup tab for any OneNote-related entries. If you find any, disable them. Also check the Services tab for "Microsoft OneNote"—if present, right-click and select Stop before disabling it permanently.

Finally, try reinstalling OneNote from the Microsoft Store. If it installs cleanly without errors, you've successfully removed all traces. If you encounter issues, repeat Step 3 and ensure no registry keys remain.

Tips & tricks for complete OneNote removal

Real talk: Uninstalling OneNote isn't as simple as clicking a button—Microsoft leaves traces everywhere. Here's what nobody tells you about getting it right the first time.

Backup First: Before diving into registry edits or folder deletions, create a system restore point. Press Windows key + R, type rstrui, and follow the prompts. This gives you a safety net if something goes wrong during the removal process. I've seen registry mistakes turn a clean uninstall into a system headache—better safe than sorry.

Timing Secret: Those 2-3 minutes in Step 1 are critical—they're not just waiting time. During this period, Windows finalizes the uninstall process and prepares to remove the main application files. If you interrupt this, you'll likely leave behind critical components that reappear later. Set a timer if you're impatient, but don't rush it.

Registry Rescue Strategy: When deleting registry keys in Step 3, take your time. I recommend exporting the registry section first by right-clicking the HKEY_CURRENT_USER\Software\Microsoft\Office folder and selecting Export. Save it somewhere safe before making any deletions. This creates a backup you can restore if you accidentally remove something important. The OneNote-containing folders are usually easy to spot, but better safe than sorry.

Office Integration Trap: Here's what nobody tells you—if you have Microsoft Office installed, OneNote often leaves integration modules behind even after uninstall. That's why Step 2 is crucial. Look for entries like "Microsoft Office Professional Plus" or "Office 365" in Programs and Features. Choosing Quick Repair instead of full uninstall ensures you remove OneNote components without breaking other Office applications.
