Read-only USB Drives for WinXP

Short tip for making USB keys read-only in WinXP:  How To Prevent Windows XP Users From Writing To USB Drives.

Expand HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control.

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.
