Prevent your window users to write on USB!
Today i was surfing on the net and found the following tip to stop user writing on USB.
Open the Registry Editor click on the Start button on your taskbar,
then click on Run and type “regedit” and click on OK to start the
From there right click and create a new key and name it
“StorageDevicePolicies”. In the window on the right then create a new
DWORD value and label it WriteProtect, give it a value of “1” and users
can no longer write to USB drives. To re-enable this option change the
value to 0 and users are again allowed to write.
The modifications you made will be in effect after you reboot your PC.
