Configure USB Disks in Read-Only mode!

How can you configure USB Disks to be Read-Only in Windows XP SP2!
This tip only works with Service Pack 2 installed in Windows XP Pro & Vista
[Note: this requires a registry modification so be sure to back up your registry or Create a System Restore point before making any changes.]
Since USB Disks-on-key and other external USB storage devices have appeared, the fact that users can transfer sensitive data from their corporate computers to their portable USB devices has caused great security concerns. Some 3rd-party software exists that can effectively block all USB storage devices throughout the corporate network, but sometimes a simpler approach is needed. To prevent users from being able to write to USB disks follow these steps:
1. Open Registry Editor.
2. In Registry Editor, navigate to the following registry key:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\StorageDevicePolicies
Note: This key might not exist. In that case simply create it as a new key under the parent key.
3. Create the following value (DWORD):
WriteProtect
and give it a value of 1.
4. Close Registry Editor.
Done!
Try to write something to any USB Disk and you'll get the error massage, but you can get any data from USB Disk.
Enjoy!

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer

3. Now in the right pane create a new DWORD item and name it NoDrives (it is case sensitive).
4. Now modify it's value and set it to 3FFFFFF (Hexadecimal) .

Now restart your computer. So, now when you click on My Computer, no drives will be shown (all gone...)!!

To enable display of drives in My Computer, simply delete this DWORD item that you created. Again restart your computer. You can now see all the drives again.
