JetBoost

JetBoost is a free and reliable solution from BlueSprig designed to optimize performance of your computer and make sure that it always is as fast as it can be. It can terminate all unnecessary processes and services to save memory and CPU, as well as determine which ones to keep depending on what you want to use the computer for (gaming or work). In addition, you can manually pick which applications to close instead of letting the program do a fully automatic job.
