In a method for improving the performance of a computer system by releasing computer resources, a list P of programs installed on a computer system is determined. All relevant extension points EP of the computer system are searched for registered entries. A list A of automatically starting programs is generated by assigning the registered entries at the relevant extension points EP to the installed programs, respectively. The list A of the automatically starting programs is compared with a list S of system-required programs and a list V of used programs. Programs that are not system-required and programs that have not been used for a longer period of time are deactivated and computer resources that have been used by the deactivated programs are released. The deactivation of programs can be done by the user or automatically and can be cancelled when necessary.
