In a computer system, one or more windows displayed on a virtual desktop of a computing device are determined to be inactive. The one or more windows may correspond to one or more processes running on the computing device. In response to determining that the one or more windows are inactive, state information for the one or more corresponding processes is saved and the one or more windows and corresponding processes are terminated. The state information comprises information for restarting the one or more processes and regenerating the one or more windows in a state that existed at a point in time corresponding to the termination of the windows and processes. A user interface is provided for restoring the terminated windows based on the stored state information.
