The ability to customize the layout and buttons on the toolbars has been removed in Windows Vista's Explorer, as has the ability to add a password to a zip file (compressed folder). The Toolbar button in Explorer to go up one folder from the current folder has been removed (the function still exists however, one can move up a folder by pressing + ). Although still fully available from the menus and keyboard shortcuts, toolbar buttons for Cut, Copy, Paste, Undo, Delete, Properties and some others are no longer available. The Menu Bar is also hidden by default but is still available by pressing the Alt key or changing its visibility in the layout options. Several other features are removed such as showing the size on the status bar without selecting items, storing metadata in NTFS alternate data streams, the IColumnProvider interface which allowed addition of custom columns to Explorer and folder background customization using desktop.ini.
