It has led to claims the device, designed to encourage youngsters to do more programming, has been "dumbed down".
Founder Eben Upton said: "We definitely want to make it easier to use. It follows "anecdotal evidence of people who have fallen off the wagon".
"The Raspberry Pi is a great platform if your parent is an engineer or you have a teacher who is an enthusiast, but if you don't have a tech-savvy adult to hand it can be quite a technical operation," Mr Upton told the BBC.
Noobs (New Out of the Box Software) comes as a compressed zip file that can be downloaded to a SD card. It offers new users a choice of operating systems to install, including ArchLInux, OpenELEC, Pidora, RaspBMC.
It could also be used to reinstall operating systems "if things go wrong", said Mr Upton. The update was just the beginning of moves to make the device more user-friendly, he told the BBC.
"For schools, we want to be able to provide a remote-reset button for teachers to use between classes," he said.
Since Raspberry Pis went on sale in February 2012, more than a million have been sold.
