Microsoft Windows XP, Microsoft Windows Vista, and Microsoft Windows Seven can do this.
Now, click 'Start' and click 'Run', type "Regedit" to open the Registry Editor, now head to HKEY_LOCALMACHINE\SYSTEM\CurrentControlSet\Control and in that folder, create new key by right-click on its screen and hover to 'Edit' then 'New' and then 'Key', name it with "StorageDevicePolicies", and on it, create new Dword with name 'writeProtect', and set its value to 1.
To enable back this function, just set the value to 2.
