On X64 based Windows operation system, unless a kernel mode driver is signed by a commercial digital certificate, windows will not load this driver module. Etefsm.sys is not signed by this type of certificate. You should change the operation system to testing mode to make windows kernel load etefsm.sys. This article shows how to enable debugging mode for windows.

Open a CMD console window, then input the following command line:

bcdedit  /set  testsigning  on 

If this command executes successfully, you must reboot Windows.
