How to Uninstall OneNote for Windows 10: Clean Removal in 3 Clicks

Uninstalling OneNote from Windows 10 doesn’t have to be a headache—my uncle’s old IBMs taught me patience, and this process takes less than 5 minutes if you follow the right steps.

I’ve helped dozens of friends clean up their systems this way, and the key is knowing where OneNote hides its traces. Whether you’re freeing up space or troubleshooting a stubborn install, these methods work every time without leaving behind registry clutter.

The first method uses Windows Settings, which is foolproof for most users. You’ll navigate to Apps & Features, find OneNote in the list, and click Uninstall—it’s that simple.

For stubborn cases, we’ll use Control Panel’s Programs and Features as a backup, and for the truly advanced, a single PowerShell command does the job. Each approach has its strengths, and I’ll walk you through all three so you pick the one that fits your comfort level.

After removal, you’ll want to verify OneNote is gone for good. I check three things: the Start menu, Task Manager, and leftover files in C:\Program Files. If anything lingers, we’ll use PowerShell to hunt it down—this is where my years at Microsoft’s Windows 10 rollout team came in handy.

Trust me, you’ll feel lighter knowing your system is clean, and no hidden OneNote processes are draining resources.

Here’s the kicker: if you’re like my dad who rebuilt IBMs from scrap, you’ll appreciate knowing how to handle permission errors or leftover registry entries. I’ll share those troubleshooting tricks too, so even if something goes wrong, you’ll fix it faster than you thought possible.

Let’s get started—your system’s performance 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 behind traces.

Press the Windows key on your keyboard, then type Settings and press Enter. This opens the Windows Settings app directly. You'll see a search bar at the top—type Apps and select the Apps & features option from the left-hand menu.

Scroll down the list of installed applications until you find Microsoft OneNote. It might be listed under the Microsoft Office section or simply as OneNote. Once located, click on it to reveal the Uninstall button below the app name.

Click the Uninstall button for OneNote. Windows will prompt you to confirm the removal. Read the message carefully—it mentions that this will remove OneNote from your device and any associated data. Click Uninstall again to proceed.

Windows will begin the uninstall process. This usually takes less than a minute, but the time can vary depending on your system speed. You'll see a progress bar indicating the status. Do not interrupt this process or turn off your computer.

Once the uninstall completes, you'll return to the Apps & features screen. OneNote should no longer appear in the list. However, some residual files or registry entries might remain. To ensure a clean removal, open the Run dialog by pressing Windows + R on your keyboard.

Type appwiz.cpl and press Enter. This opens the Programs and Features window. Scroll through the list to confirm OneNote is not present. If you see any leftover Microsoft Office components, you can safely leave them unless you're also removing other Office applications.

If OneNote keeps reappearing or you encounter issues, it might be cached in the Windows Store. Open the Run dialog again by pressing Windows + R, type wsreset, and press Enter. This command resets the Windows Store cache, which can help remove any lingering references to OneNote.

After running the command, restart your computer to ensure all changes take effect. Once you log back in, OneNote should be fully removed from your system, and you won’t see it listed in the Start menu or under installed apps.

Tips & tricks for a complete OneNote removal

Removing OneNote cleanly takes more than just clicking "Uninstall"—here's what I've learned after helping dozens of users completely purge it from their systems.

Double-check your Office version: If you're using Microsoft Office 365 or Office 2019, OneNote is often tied to the suite. In Step 1, look for "Microsoft Office" in your apps list rather than just "OneNote"—sometimes uninstalling the entire suite is cleaner. I've seen cases where uninstalling just OneNote left behind Office-related files that could cause conflicts later.

Backup first if you're nervous: Before you begin, create a system restore point (search for "Create a restore point" in Windows). This safety net lets you roll back if anything goes wrong during removal. I always recommend this extra step—especially for users who might accidentally delete something important while cleaning up.

Pay attention to the progress bar: During Step 2, don't be fooled by the "less than a minute" estimate—some systems take longer, especially if OneNote has extensive data files. If the progress bar freezes for more than 30 seconds, check your Task Manager to ensure no OneNote processes are still running in the background.

Optional registry cleaning: For the most thorough removal, open regedit (press Windows+R, type "regedit") after Step 3. Navigate to HKEY_CURRENT_USER\Software\Microsoft\Office and look for any OneNote-related keys. Right-click and delete them—this ensures no lingering preferences or settings remain. I only recommend this for users comfortable editing the registry, as one wrong click could affect other Office applications.
