Reading an INI file from the kernel driver (?)

Hi, I've read the question/answers located here:
https://www.experts-exchange.com/questions/20598910/Driver-Application-communication.html
and in general I'm aware that in the kernel mode driver you are not allowed to use CreateFile.

But, I need to read the ini file (or registry if possible) at the system startup (when the driver loads for the first time). How is this possible, if it is :)

Thanx a lot.
P.S. I've placed the 500 points for this because I think it's worth that amount.

FYI:
I have macros that use the global GXHSM_DIAG_MODE_ON for determining if logging occurs.
Example:
#if DBG //Dbg macros only log when debug version is compiled

#define DbgPrintInfo                        DbgPrint( "%p: (%5.5i) [%s] [Info]", KeGetCurrentThread(), __LINE__, __FUNCTION__);DbgPrint

//The Release log macros always log on debug version, and only log on release when switch is turned on
#define RelLoggingErrCond                  DbgPrint( "(%5.5i) [%s] [Error Condition ~~~] ", __LINE__, __FUNCTION__);if (GXHSM_DIAG_MODE_ON) DbgPrint
#define RelLoggingWarn                        DbgPrint( "(%5.5i) [%s] [Warning ~~] ", __LINE__, __FUNCTION__);if (GXHSM_DIAG_MODE_ON) DbgPrint
#define RelLoggingInfo                        DbgPrint( "(%5.5i) [%s] [Info ~] ", __LINE__, __FUNCTION__);if (GXHSM_DIAG_MODE_ON) DbgPrint

#else //Release macros log only when GXHSM_DIAG_MODE_ON is set to true

#define RelLoggingErrCond                  if (GXHSM_DIAG_MODE_ON) DbgPrint( "(%5.5i) [%s] [Error Condition ~~~] ", __LINE__, __FUNCTION__);if (GXHSM_DIAG_MODE_ON) DbgPrint
#define RelLoggingWarn                        if (GXHSM_DIAG_MODE_ON) DbgPrint( "(%5.5i) [%s] [Warning ~~] ", __LINE__, __FUNCTION__);if (GXHSM_DIAG_MODE_ON) DbgPrint
#define RelLoggingInfo                        if (GXHSM_DIAG_MODE_ON) DbgPrint( "(%5.5i) [%s] [Info ~] ", __LINE__, __FUNCTION__);if (GXHSM_DIAG_MODE_ON) DbgPrint

//This macro does nothing in release mode
#define DbgPrintInfo if (1);else DbgPrint

#endif // end DBG

If you use DebugView from Sysinternals, you can easily view above logging without having to boot the machine in special mode.
With my dirver, I'm able to turn the logging on and off without having to reboot the machine.
