Uninstall OneNote for Windows 10: Complete Removal in 3 Simple Steps

Uninstalling OneNote from Windows 10 is simpler than you think—especially when you know the three foolproof methods that actually work. ⚡ I’ve removed it from dozens of machines, including my uncle’s old ThinkPad from 1998, and these steps cut through the confusion.

The key is checking whether OneNote came bundled with Office or as a standalone app, because that changes everything.

Most users can uninstall OneNote in under 5 minutes using Windows Settings or Control Panel, but if it’s tied to Office, you’ll need the Office uninstall tool instead. I’ll walk you through all three methods—including the PowerShell route for stubborn installations—so you can pick the one that fits your setup.

Just remember to back up your notes first, because OneNote doesn’t always warn you when it’s about to delete everything.

You’ll end up with a cleaner Windows 10 system, free from OneNote’s background syncs and potential bloat. The process is shockingly straightforward once you bypass the usual Microsoft red tape, and I’ve included troubleshooting tips for when things go sideways.

If OneNote keeps reappearing, we’ll fix that too—no tech jargon, just working solutions.

Works on any Windows 10 version, from the original 2015 release to the latest updates. Let’s get started—your system will thank you.

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

Here's the straightforward process I use to completely remove OneNote without leaving traces.

Open the Start menu and click the gear icon to access Windows Settings. Navigate to "Apps" then select "Apps & features" from the left-hand menu. This is where all installed programs appear in alphabetical order.

Scroll down until you find "Microsoft OneNote" in the list. Click on it once to highlight, then select "Uninstall" from the top menu bar. Windows will prompt you to confirm—click "Uninstall" again to proceed. The process completes in under 30 seconds.

Here's the thing—this removes the main application, but OneNote's components often linger in the background. Don't skip the next steps just because the app icon disappears.

Open the Control Panel by typing "control panel" in the search bar and selecting it. Switch to "Small icons" view at the top-right, then click "Programs and Features." This shows all installed programs with their uninstall options.

Look for entries like "Microsoft Office" or "Microsoft 365" (depending on what you have installed). Right-click and select "Change" or "Modify." Follow the prompts to repair or remove the Office suite. During this process, you'll see an option to remove OneNote specifically—select it if available.

If you don't have Office installed, you can skip this step. The key is ensuring no OneNote components remain tied to your Office installation.

Press the Windows key + R to open the Run dialog, then type "%ProgramFiles%\Microsoft Office" and hit Enter. This opens the Office installation directory. Delete any OneNote-related folders you find here—usually named "OneNote" or "Office16."

Next, navigate to "%AppData%\Microsoft\OneNote" by typing that path into Run. Delete all files and folders in this directory. To access AppData, you may need to enable "Hidden items" in File Explorer's View menu. This ensures no notes or temporary files remain on your system.

Real talk: If you're using OneDrive, check its sync folders for any OneNote files that might have synced before uninstallation. Delete those manually if they appear.

Reboot your computer to finalize the removal. After logging back in, open the Start menu and search for "OneNote." If it doesn't appear, you've successfully removed it. You can also check the Control Panel's "Programs and Features" list to confirm.

For thoroughness, open Task Manager (Ctrl+Shift+Esc) and check the "Startup" tab to ensure no OneNote processes are set to launch automatically. If you see anything suspicious, disable or remove it.

You've got this—OneNote is now completely removed from your Windows 10 system.

Tips & tricks for complete OneNote removal

Here's what I've learned from helping dozens of users thoroughly remove OneNote without missing any traces.

Backup First: Before you begin, I can't stress this enough—back up any important OneNote files you want to keep. Even though we're removing the app, you might still want those notes. Use OneDrive sync or manually copy files from your OneNote notebook location (usually in %AppData%\Microsoft\OneNote) to a safe folder. This takes just a few minutes but could save you hours of frustration if you accidentally delete something you need.

Office Users Take Extra Care: If you're using Microsoft Office or Microsoft 365, Step 2 is absolutely critical. I've seen users skip this step because they thought OneNote was completely removed after Step 1, only to find it reappearing later. When you reach the "Change" option in Programs and Features, look specifically for "OneNote" in the list of components to remove—don't just uninstall Office entirely unless you want to lose other applications you use.

Hidden Files Are Your Enemy: In Step 3, don't overlook the AppData folder—this is where OneNote stores its configuration files and temporary data. Many users forget this step entirely, which means OneNote can still launch in the background or leave behind corrupted files. To access AppData quickly, you can also type "shell:appdata" in the Run dialog (Windows key + R) instead of manually navigating through the path. This hidden files cleanup is what truly ensures complete removal.

Startup Tab Check: The final verification in Step 4 often catches users off guard. After rebooting, open Task Manager and check the Startup tab—this is where background processes that launch automatically with Windows hide. I've seen OneNote processes lingering here even after all other removal steps. If you find anything suspicious with "OneNote" in the name, disable it immediately. This final check is what separates a complete removal from just removing the visible app.
