Enable or Disable ReadyBoost
To enable or enable the ReadyBoost feature in Windows 7 or Windows 8:
1. Insert the flash drive or flash memory card into your computer.
2. In the Autoplay dialog box, under General Options, click Speed up my system.
3. In the Properties dialog box, click the ReadyBoost tab, and then do one of the following:
- To turn off ReadyBoost, click Do not use this device.
To use the maximum space available on your flash drive or memory card for ReadyBoost, click Dedicate this device to ReadyBoost. Windows will leave any files already stored on the device, but it will use the rest to speed up your system.
To use less than the maximum available space on your ReadyBoost device, click Dedicate this device to ReadyBoost, then move the slider to choose the amount of open space on the device you want to use.
4. Click Apply> OK.
For ReadyBoost to speed up your computer, the flash drive or memory card must be at least 1 gigabyte (GB). If your drive or card doesn’t have enough space for ReadyBoost, you’ll see a message telling you to free up some space on it. For best results, use a flash drive or a flash memory card with at least twice the available area as the memory (RAM) in your computer.
