USB drives are extremely handy
tools, but in some instances it might not be a good idea to allow
users to write onto these devices from their PCs. This is
especially true when working with highly confidential data or
intellectual property at work; what if the information gets into
the wrong hands because of a disgruntled employee?
Microsoft has acknowledged this potential security threat and
users of Windows XP with service pack 2 installed can disable
writing to USB devices.
To do this, follow the next steps:
- 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 regedit utility.
- 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
