HKEY_LOCAL_MACHINE>>SYSTEM>>CurrentControlSet>>Control>>StorageDevicePolicies. Double click the key WriteProtect in the right pane and set the value to “0” In the Value Data Box and press OK button. Exit Registry menu and restart your computer once and try to connect the USB again. This is the simplest and easy way to remove the write protection but if the USB still has the same problem then better to follow the Tool based technique.
