Cakewalk is the current name of the company that develops Sonar and other music software http://www.cakewalk.com/
Actually the Sonar software has been around since several years now, and the latest version is called Sonar X3.
I think it's quite unlikely you didn't use a previous version of Sonar even on a 10 year old pc.
However, Cakewalk was also the name of a software sequencer developed by Twelve Tone Systems Inc. http://en.wikipedia.org/wiki/Cakewalk_%28sequencer%29
Confusingly enough, in 1999 the company Twelve Tone Systems Inc. changed their name into Cakewalk, while at the same time changing the name of their software Cakewalk into Sonar...
Hope this helps.
