cant update

Quit OneDrive from its taskbar menu, run the Avast update, and then reopen OneDrive from the Start menu.

Close OneDrive completely

1. At the bottom-right of the Windows 11 taskbar, select the OneDrive cloud icon.
   • If it is hidden, select the ^ arrow first.
2. Select the gear icon (Help & Settings).
3. Select Pause syncing → Quit OneDrive.
4. Confirm Quit OneDrive if prompted. This closes the application rather than merely pausing synchronization.^1^
5. Check that the cloud icon has disappeared from the notification area, then retry the update in Avast.

You do not need to unlink your account or uninstall OneDrive.

If Avast still says OneDrive is open

1. Press Ctrl+Shift+Esc to open Task Manager.
2. Select Processes.
3. Find Microsoft OneDrive.
4. Select it, and then select End task. Task Manager can terminate a process that remains running after its window or taskbar icon closes.^2^
5. Confirm Microsoft OneDrive no longer appears in the process list, then retry the update.

After the update finishes, press the Windows key, type OneDrive, and open the app. Synchronization should resume.^1^

If the Avast message names an application other than Microsoft OneDrive, close that exact application instead.
