Used GuitarSim for Windows?
Developer’s Description
GuitarSim is a guitar-simulation program that allows you to play tunes on a virtual guitar. Improvise and make your own melody or try to play your favourite song.
The 1 to = keys on the keyboard are used as frets while the right shift allows you to strum the guitar, so playing around in GuitarSim takes some skill, but you will get the hang of it quickly.
