The free OSR Learning Library has more than 50 articles on a wide variety of topics about writing and debugging device drivers and Minifilters. From introductory level to advanced. All the articles have been recently reviewed and updated, and are written using the clear and definitive style you've come to expect from OSR over the years.

It appears that something was changed recently and a new privilege is required for these? My app enables SE_LOAD_DRIVER and SE_SECURITY privileges, AdjustTokenPrivileges return TRUE, and GetLastError returns ERROR_SUCCESS (so it's not ERROR_NOT_ALL_ASSIGNED, which is probably everyone's first idea, myself included).
Does anyone know what is up? Fltmc Unload works of course, and the unload works on some Vms, but not all.
