Unlike its predecessors, Windows 7 explorer does not display buttons to Copy, Paste or Delete files and folders in the Explorer command bar although you can access these options from the Organize menu. But if you wish, you can add Copy, Paste and Delete Buttons to Windows 7 explorer folder band with the help of this registry hack.
To do so, first you will have to take full control of this registry key.
Next, after creating a system restore point, open registry editor as admin, and navigate to the following key:
In the right side pane, right click > New > Key. Name the subkey as TasksItemsSelected and give it a value:
Windows.Copy; Windows.Paste; Windows.Delete;
These values correspond to the buttons Copy, Paste, and Delete.
Now restart or refresh Windows Explorer and select any file.
You will see these options now!
