Answer 2

Prefetch id used for boot up - The Prefetcher is a component of versions of Microsoft Windows starting with Windows XP. It is a component of the Memory manager that speeds up the Windows boot process, and shortens the amount of time it takes to start up programs. In Windows Vista, SuperFetch and ReadyBoost extend upon the prefetcher and attempt to accelerate application and boot launch times respectively by monitoring and adapting to usage patterns over periods of time and loading the majority of the files and data needed by them into memory so that they can be accessed very quickly when needed.

Drwtsn.exe is supposed to be there as well , however there is spyware out  there that will cause it to do odd behavior thus crashing your pc etc.. go get an antivirus ( avast.com ,, avg.com ) and run a deep sweep.
