Hi, I a product which uses a minifilter driver to do some tasks but in a few Win 10 machines, I get error 87 (invalid parameter) when I try to start the driver. It is signed both by my EV SHA2 certificate and Microsoft Hardware Portal.
We could figure out kernel is refusing to load the driver but when trying to determine why...
Show Loader Snapswith
gflagsutility. The kernel & system tabs' checkboxes get unchecked after pressing the save button so I have to modify the registry directly by adding
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Sessionand enabling, just in case, legacy debug output by adding the
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Debug Print Filterbut still loader does not output anything!
Any hint on how to get any debug output? May be running LiveKD because I cannot attach a kernel debugger to the computer.
