Hi DELL4U, if you want to disable USB flash drive on the computer, you can simply disable this by using the restriction:Set Computer Restrictions | Security Settings | Prevent write access to USB storage devicesI'd also like to inform you that we cannot use Windows SteadyState to disable "copy" function in Windows. For system related inquiry, you can post to the following forums: http://social.technet.microsoft.com/Forums/en/category/windowsxpitpro http://social.technet.microsoft.com/Forums/en/category/windowsvistaitpro Hope this helps!Sean Zhu - MSFT
