Hello, I’m Virginia, a fellow user like yourself. I’m in the UK.
Sorry to hear you’re experiencing problems. May I ask which Windows 10/11 build are you running - 22H2 (Win 10/Win 11) or 23H2 (Win 11)?
I understand you’re having problems with a box icon on files/folders, Don’t worry as I’ll do my best to assist you today.
The box icon sounds like it could be a shortcut for ‘files on demand’ which is a OneDrive & Dropbox icon.
A brown box over your Windows Desktop icons can be caused by an issue with Windows Explorer.
To resolve the issue, restart Windows Explorer:
Press Windows key + E.
Press CTRL + ALT + DEL and select Task Manager.
Select More details to show all the apps.
On the Processes tab, under Apps, right-click on Windows Explorer.
Select Restart.
