Another "issue" with CIS that has been around for a long time. (Since v6.) This might be intractable, since, in a sense, HIPS is doing exactly what it's supposed to do. Here's the issue:
I just updated some drivers. Some installers/updaters - like those from RealTek, use an old fashioned DOS like installer from Windows 3 days. The installer requires a reboot to finish installing the new driver. (Since it uninstalls the old driver first and has to reboot to clear out old startup stuff and/or to release the old drivers from use.)
So when the Installer finishes part One of the install, and while Windows is shutting down, I hear a ding sound as HIPS detects something trying to run. Like, maybe the "restart the installation after reboot" command? (I don't know because it happens so fast, and Windows shuts down so fast, that I can't see the CIS Alert.)
I also get this behavior after installing Nvidia drivers. Apparently there's something that Nvidia wants to do to its "Container" when Windows is shutting down.
On days when I'm smart, I've learned to set HIPS to Disable when installing new drivers. (Although that's not very satisfying, because some companies try to sneak other stuff in during an install.) On days when I'm not smart, I have to restore a previous image and then try to be smart during the install.
I think there's a Registry Hack that will delay the Windows Shutdown process. If so, perhaps CIS could invoke that (as an option?) whenever an HIPS Alert pops up during the Shutdown sequence?
