Uninstalling OneNote for Windows 10: Step-by-Step Data-Safe Removal

To uninstall OneNote from Windows 10, start by backing up your notes—this isn’t just smart, it’s essential. ✨ I’ve seen too many users skip this step and panic when their data vanishes during the process.

OneNote ties itself into Office apps, so we’ll need to handle that carefully before we begin.

Grab a USB drive or cloud storage for your notes, then check if OneNote’s tied to Office 365—if it is, you’ll need to remove it through the Microsoft Store first. The Control Panel method works for most users, but PowerShell comes in handy when things get stubborn.

I’ve used both methods hundreds of times, and they’re both reliable when done right.

Once uninstalled, verify it’s gone by searching for OneNote in the Start menu—nothing should appear. If remnants linger, a quick registry cleanup with CCleaner or manual deletion of leftover folders will finish the job. This method keeps your system clean and your data safe, even if OneNote fights back.

Common pitfalls include Office integration errors or leftover shortcuts. If OneNote keeps reappearing, check your Office installation—sometimes it’s hiding there. I’ve documented every troubleshooting step in the full guide, so you won’t get stuck.

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

Here's how to cleanly remove OneNote while keeping your notes safe and system intact.

Open OneNote and click File in the top-left corner. Select Open and choose OneDrive or PC depending on where your data is stored. Right-click the notebook you want to preserve and select Export to create a backup file.

I always recommend exporting to a OneNote Package (.onepkg) file or as a PDF—this ensures your notes, drawings, and formatting stay intact. Save the backup to an external drive or cloud storage before proceeding. This step prevents accidental data loss if something goes wrong during uninstallation.

If you're using OneNote with a Microsoft account, your data may already sync to OneDrive—double-check by signing in to OneDrive.com and verifying your notebooks appear in the OneNote folder.

Press the Windows key + I to open Settings, then navigate to Apps and select Apps & features. In the list, find Microsoft OneNote and click it to expand the details.

Click Uninstall and confirm by selecting Uninstall again in the confirmation dialog. Wait for the progress bar to reach 100%—this typically takes 30-60 seconds. The system will automatically remove the app and its core files from your device.

If you don't see OneNote in the list, it might be installed as part of the Microsoft Office suite. In that case, uninstall Microsoft Office instead, then reinstall the other Office apps you need separately.

Open File Explorer and navigate to C:\Users\[YourUsername]\AppData\Local\Microsoft\OneNote. Delete the entire OneNote folder here—this removes cached data and temporary files. If prompted for confirmation, select Yes.

For a deeper clean, press Windows key + R, type regedit, and press Enter to open the Registry Editor. Navigate to HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\OneNote and delete the entire OneNote key. Close the Registry Editor when done.

Real talk: Skipping this step can leave behind leftover files that might cause conflicts if you reinstall OneNote later. I've seen cases where old settings caused crashes or corrupted notebooks—better safe than sorry.

Restart your computer to finalize the uninstallation process. After rebooting, open the Start menu and search for OneNote—it should no longer appear in the list of installed apps.

Check your Desktop and Taskbar for any lingering OneNote shortcuts or pinned tiles. Right-click and delete them if they appear. For a thorough cleanup, use Windows Search to find and delete any remaining OneNote.lnk files.

If you plan to reinstall OneNote later, you can do so by downloading it from the Microsoft Store or through your Office subscription. Your backed-up data will remain safe and can be restored by importing the exported file.

Tips & tricks for clean OneNote removal

Took me a while to figure out the safest way to remove OneNote without losing important notes or leaving behind system clutter. Here are the key strategies I've learned that make all the difference.

Backup First, Always: Don't skip creating that backup in Step 1—this is your safety net. I've seen too many people skip this step and panic when they can't find their notes after uninstalling. The OneNote Package (.onepkg) format preserves everything perfectly, including handwritten notes and drawings. If you're unsure where your notebooks are stored, check both OneDrive and your local PC storage locations before proceeding.

Office Suite Consideration: Here's what nobody tells you—if OneNote disappears from your Apps list, it might be bundled with Microsoft Office. In Step 2, when you don't see OneNote standalone, uninstalling the entire Office suite is sometimes necessary. The good news is you can reinstall just the apps you need later. I recommend keeping Word and Excel if you use them regularly, but you can skip the full Office suite if you only need OneNote removed.

Registry Cleanup Matters: Skipping Step 3's registry cleanup might seem harmless, but I've seen cases where leftover registry entries caused OneNote to crash when users tried reinstalling later. The path HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\OneNote is where OneNote stores its settings. If you're uncomfortable editing the registry, at least delete the AppData folder—it removes most of the lingering files that could cause problems.

Post-Reboot Checklist: After that restart in Step 4, do a thorough scan for OneNote remnants. I always check these three places: the Start menu search results, the Desktop for any shortcuts, and hidden files using Windows Search. You'd be surprised how many people miss the .lnk files that can still launch OneNote accidentally. Pro tip: Use the search bar in File Explorer and type OneNote to find any hidden files.
