Microsoft 文件托管和同步服务。
Hi,
I understand the issue may be related to OneDrive or File Explorer. Since you have already tried troubleshooting OneDrive without success, please try restarting Windows Explorer.
- Please right‑click on your taskbar and select Task Manager.
- In Task Manager, go to the Processes tab and look for Windows Explorer.
- Right‑click Windows Explorer and choose Restart.
- Wait a few moments, then close Task Manager.
- Restart your PC and check if the box disappears.
Please let me know how it goes.
Stay Safe!
