How to remove widget from kubuntu [duplicate]

I'm completely new to Linux. I had no choice but to install a Linux distro to my desktop (I couldn't run my old Windows XP hard drive on my new [second hand bits] Frankenstein) computer, so I googled the best distros for audio recording and Ubuntu Studio was at the top of the list. I have, as expected, several issues to sort out but for now, the most annoying is that I tried putting a widget on desktop to have quick access to other drives. A box landed on my screen and now I can't get rid of it. I tried by going to widgets again, all I succeeded in doing was dropping the same widget onto my desktop twice more. Right click on the widget does nothing at all and Enter Edit Mode turns up grey and won't allow me to click on it. Please help!

Solution 1:

Right click on the desktop and enter edit mode.

Now hover on the widget, and you would find the remove (bin) button.
