I have just encountered two of my customers that had the webfiltering rolled out to them recently, and both user's Win7 X64-based systems have webfiltering active/working in IE (10 and 11), but for some reason, on both systems, Chrome does not have the extension for the webfiltering active. I have had the users: 1) Uninstall WSA and then reinstall WSA. 2) Uninstall Chrome and reinstall it. Neither of these actions helped. My concern is that this might be (substitute: must be) happening to other users as well.
