With Windows 7, Microsoft has introduced Libraries: a wonderful feature of the Explorer shell, which allows you to group multiple folders in a single view, even if they are located on different volumes. Searching through Libraries is also very fast, because Windows performs indexing of all locations which are included inside a Library.
If you use Libraries regularly, you might have noticed that when you open the Properties of a folder to change its icon, you are unable to do so because the Customize tab is missing from the folder's properties.
