I've used both. With enditall, it ends programs you want stopped, much like going thru the task manager, but less intimidating.
With FSAutostat/Alacrity PC you set up a profile once. After I set my profile, I would then click my desktop icon. The program would then shut down everything I had requested, defrag my ram, and then start the game. When I closed out of the game it would restart all of the programs I requested to be restarted.
The difference is that when using my computer as a web design station I need certain things running, as a cartoon pilot, I need other things. With this program I can configure the computer better to which ever task I'm looking to do WITH OUT rebooting it all the time.
....oh and Mr Ripley, not everyone can afford to upgrade their computer when ever they want, and this program is a nice cheap (free) work around to get the job done. It has gotten me an extra year or two on some of my old computers.
