To remove write protection from a USB flash drive, open the Start menu on your computer, and click run. When prompted, type in "regedit," and press enter to open the registry editor. Next, navigate to the storage device policies within the control section of the system. Find the write protect key on the right side of the pane, and double click on it. Set the value to zero, and press OK in the data value box.
To finish removing the write protection from a flash drive and begin using it, restart your system, and reconnect the flash drive to the computer. If a USB drive gives the message that the disk is write-protected and to remove the write protection, another tip is to check it for viruses. A virus can fill a USB drive with unwanted files. Configure your antivirus software to automatically scan USB drives, or right-click on the USB drive icon in Windows Explorer to perform a manual scan.
Other troubleshooting advice to remove write protection on a flash drive includes checking the body of the drive for a mechanical switch that engages write-protected mode and checking to see if the flash drive is at maximum capacity. Also check to see if a certain file has write protection as opposed to the entire flash drive.
