Abstract

It will be provided with an information processing apparatus, an information processing system, a computer program and an information processing method, which can prepare operating environment based on setting information distinctive in respective users without causing interference on operating environments for other users.

A controlling unit 10 of the information processing apparatus 1 can implement plural virtual PCs. When receiving a request for activating a virtual PC from a terminal apparatus, the controlling unit 10 obtains setting information from the terminal apparatus. The controlling unit 10 determines whether the setting information obtained from the terminal apparatus falls into acceptable range based on constraint conditions being set by a setting acceptable range template 13d. When having determined that the setting information falls into the acceptable range, the controlling unit 10 activates the virtual PC based on the setting information obtained from the terminal apparatus.
