If you have a spare U.S.B. flash drive with at least 256 megabytes of free space on it, you can use it to give your Windows Vista-operated PC an extra cache of memory to help increase speed, using the Windows ReadyBoost feature. Just plug the drive into a U.S.B. 2.0 port, and if it is fast enough to work with ReadyBoost, the system will prompt you to set it up.
