Use the restart command in the Command-Line Debugger Shell, after stopping program execution. The debugger goes back to the beginning of the program and begins execution again.
Right-click Thread in the Debug view and choose Restart from the shortcut menu.
Click the Restart button in the Debug view toolbar to restart debug session.
Note: Restart action is considerable faster to relaunch a debug session as it skips over loading executable debug information and target register descriptors.
