AlacrityPC is a utility designed to help you get the most performance out of your computer when running resource intensive applications, like modern games. It does this by shutting down unnecessary services and programs before starting your application. When you finish your application, those services and programs can be automatically restarted. AlacrityPC also provides some additional optimizations, like memory defragmenting, removing your desktop background, shutting down the desktop shell and Vista Sidebar, and forcing background tasks to execute. AlacrityPC is the sequel to FSAutoStart. It is written in C# .NET 2.0.
