A simple user-mode driver that sends the "Hello there!" message to the kernel debugger.
Make sure you have the Tracelog tool on your target computer. The tool is located in the <install_folder>Windows Kits\10\Tools<arch> folder of the WDK.
Open a Command Window and run as administrator.
Type the following command:
tracelog -start MyTrace -guid #c8d7d28f-5d1a-4ae1-96c2-7b02bc5412d1 -flag 0xFFFF -level 7-rt -kd
The command starts a trace session named MyTrace. In the Debugger Immediate Window you will see Hello there!
You can stop the trace session by typing the following command:
tracelog -stop MyTrace
The output should be similar to the following.
