ramasst.exe is a process that is installed together with common DVD drives. It is used to disable the XP built-in CD burning functions.
This process should not be removed if you do not have a problem with your CD/DVD burning applications.
Non-system processes like ramasst.exe originate from software you installed on your system. Since most applications store data in your system's registry, it is likely that your registry has suffered fragmentation and accumulated invalid entries which can affect your PC's performance. It is recommended that you
check your registry to identify slowdown issues.
