Confirmation of file delete
In Windows 8, Microsoft has removed the automatic file deletion confirmation in File Explorer.
To turn it back on, go to Recycle Bin (on the desktop) and right-click the icon. Then left-click on Properties.
The last item on the dialog will say "Display delete confirmation dialog", so put a tick in that box. Click OK, and that's done.
You might imagine that the confirmation will apply only to items being deleted from the Recycle Bin. But is also allows confirmation when a file or folder is being deleted from File Explorer.
