With the newest version of Windows, named Windows Vista, came many handy features. One of these new features is called “ReadyBoost” and it is designed to improve performance. The only requirement to using ReadBoost is that you have a ReadyBoost capable flash drive and Windows Vista.
To enable ReadyBoost:
Open the start menu, select “computer” and find your flash drive. It will usually be called a “removable disk”
Right click on the flash drive and select “properties” It should open a box like this.
Select the “ReadyBoost” tab and select “Use this device” Below that you can choose any size you wish. Microsoft recommends 4GB for optimum performance but if you do not have enough space on your flash drive you can use less.
Click apply and Windows will begin creating a ReadyBoost file on your flash drive. This file will be whatever size you chose, and it will be named ReadyBoost Cache File. Make sure not to delete this file unless you want to stop using ReadyBoost.
After that you are done. Windows Vista will automatically begin using the space on your flash drive as a swap file, similar to the way it uses RAM. This should improve the speed of your computer, as well as make programs run smoother and open faster.
As with most changes to computer software, it is very easy to change back. If for any reason ReadyBoost seems to slow your computer down, simply open the ReadyBoost tab again and select “Do not use this device” This will disable ReadyBoost, and free up the space on your flash drive.
