Limiting computer copying files to USB Flasdisk

Several reasons for computer owners to restrict his computer so can not save data to USB flash disks, There are several tools scattered on the internet, but it certainly will add a burden to your computer's performance.
For that I am trying to provide another alternative to the registry settings, this applies to Windows XP, for Windows 7 I have not tried it
For security reasons, you can prevent the computer storing the data to a USB drive, how:
1. Click Start and select Run. Type "regedit" (without the quotes) and click OK.

2. Find address HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control.



3. In the right pane, right click and create new keys (New Key) with the name "StorageDevicePolicies".

4. In the left pane, select the newly created StorageDevicPolicies earlier. Create a new DWORD value and name it "WriteProtect".

5. Change the value to "1". Close the editor and restart the computer.

Note:

To restore its original pal only replace the Value Data from key "WriteProtect" to 0, to reactivate Block 1 USB input

you still can copy and paste files from a flash or other devices that use the media to your computer USB port, but not vice versa.
Hopefully helpful
