The deskband (CDS Toolbar) has been removed from the software in version 4. However, we added a shortcut keyboard command so you can access the main search window with the focus in the search field by using keyboard stroke -> CTRL + CTRL. This can be triggered on or off from the menu tools -> Options -> Advanced.
This feature was asked by a lot of users who had tried Google desktop so we decided to put that in place instead of the deskbar, which was not always behaving properly with the latest windows updates.
I also used the search box that feature extensively. Can it be put back as an option? Is there any reason why the keyboard shortcut and the search bar cant exist leaving the user the option to use one or both?
