How can i remove write protection from my usb

Have a look in the device's Properties - particularly under Autorun options. Sometimes there's an option to toggle on and off in there.

Hello jerry_32 and welcome to Tom's Hardware Forums.

I just want you to know I wholeheartedly agree with your substantial and most illuminating post.  

Just in case that the problem is n your system and not the USB flash drive, you can try this solution..

Go to run->Type Regedit
Search into "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control \StorageDevicePolicies"
Double click to open Write Protected File and and change the value into " 0 " then click ok.
Insert your device and check it.
