Hi mem,

There is no folder with the name of "Services" under CurrentControlSet in the following path in WinXP SP2. I think it will be in WinXP SP3.
Any how thanks for your advise.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\UsbStor

"Warning : Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk. If a USB storage device is already installed on the computer"

set the Start value in the following registry key to 4:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\UsbStor

When you do so, the USB storage device does not work when the user connects the device to the computer.

To set the Start value, follow these

steps:1. Click Start, and then click Run.
2. In the Open box, type regedit, and then click OK.
3. Locate, and then click the following registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\UsbStor

4. In the right pane, double-click Start.
5. In the Value data box, type 4, click Hexadecimal (if it is not already
selected), and then click OK.
6. Quit Registry Editor.

Let me know How it worked for you.

Regards,
Sridevi

Hi Friend,

value 3 is for enable & value 4 is for disable the usb drive.
To disable thre drive give value 4.

If this method doesn't work for you, you can try going into device manager and under USB controllers you can try disabling them from there.

If neither of those methods work then go into your computer BIOS and disable the USB ports.

Regards,
Rijus.
