How to disable or block use of USB flash drives to avoid copying in windows

Posted by Aamir
In this post we will be looking at how to block or disable use of USB data storage devices so that no data on your computer gets copied. Once you disable write access to USB ports, any external USB device connected to computer appears as Read only. Here Read only means you will be able to connect and use USB devices like Keyboard, USB mouse, USB joysticks but will not be able to copy data from your computer to external USB storage devices like pen-drives, memory cards and external hard disks. You can disable write access to USB ports either by tweaking Windows Registry which does not require any software or by using any third party Software. The effective way to do this is to Tweak Windows Registry settings as it does not require any software. Below I provided step by step procedure on how to tweak windows registry settings to disable write access to USB ports and also how to block USB ports using a third party software.
