How to Fix a White Box Above the Taskbar Caused by OneDrive
Question details
A persistent white box appears on the screen just above the taskbar when the OneDrive client is running.
- Product
- Microsoft OneDrive
- Device & OS
- Windows 10
- Scenario
- Running the OneDrive desktop client for background file synchronization.
- Observed behavior
- A blank white box persistently overlays the screen space directly above the taskbar. Standard environment variable changes and basic troubleshooting do not remove the visual glitch.
Before making changes to the Windows Registry or uninstalling OneDrive, verify that all your currently syncing files have finished updating to the cloud to prevent version conflicts.
Reset the OneDrive Client
Resetting the OneDrive client can often clear cached UI elements and display glitches without requiring a full reinstallation.
A simple client reset forces OneDrive to restart its background processes, which is frequently enough to clear UI bugs like the taskbar white box.
Press the Windows key + R simultaneously on your keyboard to open the Run window.
Type `%localappdata%\Microsoft\OneDrive\onedrive.exe /reset` and press Enter. If you see a 'Windows cannot find...' message, try using `C:\Program Files\Microsoft OneDrive\onedrive.exe /reset` instead.
Wait for the OneDrive cloud icon in your taskbar to disappear and re-appear. If it does not reappear after a few minutes, open the Start menu, search for 'OneDrive', and click it to launch the app.
Delete OneDrive Registry Configuration and Reinstall
If a simple reset fails, completely clearing OneDrive's registry settings and performing a fresh installation will permanently resolve the taskbar white box issue.

Frequently Asked Questions
Will deleting the OneDrive registry key delete my cloud files?
No. Deleting the registry key at HKEY_CURRENT_USER\Software\Microsoft\OneDrive only removes your local application configuration and preferences. Your actual files, both local and in the cloud, remain completely safe and untouched.
Why does OneDrive cause a white box above the Windows taskbar?
This is a known visual rendering bug in certain builds of the OneDrive desktop client. It typically happens when an invisible UI element, such as a sync status prompt or an account sign-in overlay, fails to load or close properly.
How can I find out which version of OneDrive I am currently running?
Click the OneDrive cloud icon in your taskbar, select the gear icon to open 'Help & Settings', click on 'Settings', and navigate to the 'About' tab. There you will see the exact build number you have installed.
What should I do if the Registry Editor says I don't have permission to delete a key?
If you receive a permission error, make sure you opened the Registry Editor with administrative privileges. Press the Windows key, search for 'regedit', right-click the application, and select 'Run as administrator'.
