I just installed pg and have been reading the help files and this group. It seems to be working pretty well, but I'm confused about some of the options listed in protection/general protection options. Some of them, such as Block end task from terminating applications, seem to be set as part of the 'blocked' options for each application that is listed in pg. Does that one, for example, have to be ticked in protection/general protection options before it can be used in the individual applications, or is it something different? From articles here, it looks like Block Global Hooks should be turned on, but what of the others? I haven't seen mention of them: Block dll files from being added to appinit_dlls registry key Block drivers and services from installing Block end task from terminating applications. thanks. It looks like an excellent product.
