    Hi all,
    Can any body tell me the good example or link for upper-level class filter
    driver. I have to run that upper-level class filter driver from user
    appliction ( through CreateService etc). I have to make it nonpnp filter
    driver as pnp filter driver does not Start service from user appliction and
    get unload.So basically i want non pnp upper-level class filter driver
    Thanks in advance

  3. You cannot add nonPnP filters to PnP stacks without causing issues.

    So, add a PnP filter, let it be always loaded while the stack is up, and
    the app will switch it to do nothing pass-through mode instead of unloading it.
