Disappointed that your pendrive does not support Readyboost on Windows Vista? Ok… a bit of basics first for those who dont know what is Readyboost. Readyboost is a technology in Windows Vista that enables the system to speed up by plugging in a USB pen drive instead of adding a RAM module. In this way you dont have to spend much on costly RAMs. But remember that you need a pen drive with good data transfer rate or else this would only slow down Vista.
Ok time to get our hands dirty. Follow the steps and dont forget to back up the registry before starting…
1. Plug in the device.
2. Open the Readyboost tab on the device properties.
3. Select “Do not retest this device”
4. Unplug the device
5. Open regedit (start->run->regedit)
6. Expand – HKLM (Local Machine)->SOFTWARE->Microsoft->Windows NT->CurrentVersion->EMDgmt
7. Find your device.
8. Change Device Status to 2
9. Change ReadSpeedKBs to 1000
10. Change WriteSpeedKBs to 1000
11. Plug in the device.
12. Enable Readyboost!!!!
You may need to take out the device and plug it back in once more for readyboost to show up under properties. Thats all and you are done.
