AlomWare - 513KB (Commercial Trial)
AlomWare Reset is a simple app that works by rapidly closing all open apps and windows, clearing the clipboard and recent document lists, killing non-system processes, freeing memory and defaulting other settings to their clean booted-like state.
When running the app, a warning message is displayed in the interface. If all your data is saved, you can proceed and reset your system, but if you want to perform another task, you can simply close AlomWare Reset and start it again when you need it.
The app can simulate the effects of a regular reboot, without actually restarting the OS. Because of this, the reset time is reduced to a few seconds and you should end up with a fresh system to work on.
