www.BlackViper.com: Windows Vista Service Pack 2 Services 411 - Superfetch

Superfetch

Default Description:

Maintains and improves system performance over time.

Additional Information:

Superfetch Service along with ReadyBoost service and an USB flash drive or memory card is used as additional RAM. If you do not use an USB flash drive in this manner, you can disable ReadyBoost, but I recommend to leave the Superfetch service on Automatic.
