3: Create a Dword value named WriteProtect and set its value to 0
4: Restart the above is a normal operation, but in actual operation, the above operation sometimes cannot solve the write protection problem. Then continue the following operations:
5: Restart with the U disk when restarting. When the system restarts until the U disk light flashes, unplug the U disk
6: After the system restarts, insert the U disk. The U disk operation returns to normal. Additional explanation:
