How do I close superfetch?

Windows8/windows 8.1 's SuperFetch Super pre-read service is designed primarily for enterprise applications and large collaborative software, and is not necessary for individual users to open. Enterprise policy Management and other professional software used in large enterprises, the database startup process is often up to 10 minutes long, and the use of SuperFetch Super Read service can reduce start-up time to less than 6 minutes. But for our individual users, usually use the software startup time is very short, usually in 1-2 seconds, SuperFetch Super pre-read service even if speed is only 0.2-0.5 seconds, this time we can generally ignore, and open the service, will only increase the monitoring of the hard disk (loss of CPU performance time and read time (increase HDD IO addressed thread allocation), which is also the root cause of complaints about hard disk occupancy.
