Today early morning one of my friends called me for urgent help. He is working as a System Administrator for a small company and wants to disable copying files from working computer to USB drives (pen drives). I told him to disable the USB port and fix the issue. Then he said according to the company policy he cannot disable it. He wants the computer should read files from the USB drive but no file transfer to it from computer hard disk. So, in a nutshell, he wants to read files from the portable storage drive on his company computers but does not want to copy files from his company computer to the USB drive. He is confused that if it is possible to block writing files to the portable memory storage without preventing the PC from reading it.
I too at first confused with this strange company policy. Then I realize, it is very simple to do. We can enable write protection on USB by GP edit or Registry Edit. If Write Protect is enabled on Universal Serial Bus, the computer can read files on portable storage but not able to copy content to them from the hard disk. It is very simple to enable write protection on USB Ports from registry and group policy editor.
On Windows 7 and Windows 10 computers, the easiest method to disable copying to USB storage without preventing reading is to enable "Removable Disks: Deny Write Access" on Local Group Policy Editor. If you do not know how to do it, follow the step by step instructions.
