Question details
The user is experiencing an issue where OneNote for Windows 10 continues to run in the background, but the application window randomly fails to display when clicked from the taskbar or task switcher.
- Product
- OneNote for Windows 10
- Device & OS
- Windows 10
- Scenario
- Switching back to the active OneNote application via the taskbar or Windows task switcher during daily workflow.
- Observed behavior
- The OneNote window remains hidden and does not appear on the screen, even though the application is running. Standard fixes like repairing, resetting, or reinstalling the app do not resolve the issue.
Ensure you have saved your recent work in other applications and verify if you have administrative privileges on your device, as some troubleshooting steps may require IT approval on work computers.
Update Windows 10 and Test User Profile
Updating your operating system and testing a different user account can determine if the display glitch is caused by a corrupted Windows user profile.
Window rendering issues with Universal Windows Platform (UWP) apps like OneNote for Windows 10 are often tied to specific user profile corruptions or outdated system components.
Open the Windows Start menu, click on the Settings gear icon, and navigate to 'Update & Security'. Click 'Check for updates' and install any pending Windows 10 updates, then restart your PC.
If you have administrative rights, go to Settings > Accounts > Family & other users, and select 'Add someone else to this PC'. Log into this new account and open OneNote to see if the window appears normally.
If you are on a work computer and cannot create a new account, contact your IT department and ask them to test your profile integrity or recreate your Windows user profile.
Collect System Details and Report the Issue
If standard repairs fail and the issue is strictly isolated to OneNote, gathering system diagnostics is necessary for escalation.

Frequently Asked Questions
Why does OneNote show as running but the window won't open on the screen?
This usually occurs due to a glitch in the Windows 10 Desktop Window Manager, a corrupted user profile, or a bug in the Universal Windows Platform (UWP) preventing the interface from rendering properly when called from the taskbar.
Will resetting or reinstalling OneNote fix the taskbar display issue?
Not always. If the issue stems from a deeper Windows OS problem or user profile corruption, standard app-level troubleshooting like repairing or reinstalling OneNote may fail to resolve the taskbar issue.
How can I force close OneNote if it's stuck running in the background?
Press Ctrl + Shift + Esc to open the Task Manager. Find 'OneNote' under the Processes tab, right-click it, and select 'End task'. Afterward, try reopening the app from your Start menu.
What should I do if my work computer won't let me update Windows or add users?
You should document your specific system details by running the 'winver' command, write down the behavior you observe, and submit a support ticket to your company's IT department so they can perform the necessary administrative steps.
