This type of rules kind of risky as if we given a folder path, any files in that particular folder affects from this rule.įile Hash: This criteria is apply to allow or block applications which is not digitally signed. Path : Using this criteria we can block or allow applications based on the specific folder or file path. Publisher: Using this criteria we can block or allow applications based on its digital signature publish by the software publisher. in each of these containers we can allow or block applications based on 3 criteria. Lets look in to furthure in to this nice feature.Īs explain in part 1 in group policy applocker container there are four nodes called executable rules, windows installer rules,script rules and packaged app rules. In Part 1 i have explain what is "AppLocker" and use of it. If you still not read the Part 1 you can find it in here. So in the end the answer is not to difficult, but unless you go digging in to the fact that modern apps are treated differently by AppLocker and GPO’s will disable the service before cleaning house, then this blog may be useful.This is the Part 2 of the AppLocker series. Short answer was to keep the GPO’s enabled but remove ALL of the Applocker rules, refresh the GPO’s several times until the Packaged apps start to work again and then you can remove the GPO. Turns out that when you remove the GPO from workstations the Applocker service gets disabled before it can update it’s policies so the policies remain intact. It is almost as if once the Applocker rules are applied they are never removed.Īfter a little more digging I found this article: Problem: AppLocker Rules Still Enforced After the Service is Stopped However, after removing the GPO, refreshing the GPO’s (GPUpdate /force) and rebooting several times the error still occurs. exe based rules, Windows will automatically disable ALL modern apps unless unlocked by specific AppLocker rules. These rules target the new Modern UI style apps. Under Windows 8.x and 10, the new applications require new AppLocker rules called Package App Rules. Looking at the event logs, the AppLocker event log reads: “ No packaged apps can be executed while Exe rules are being enforced and no packaged app rules have been configured” Now I know I have some AppLocker GPO’s in the environment that prevent users from running applications under their user folder (C:\User\Username) but that does not explain why these apps are not running as they are not run from one of these locations. Before they join the domain all apps are functioning fine, however, as soon as one of them joins the domain ALL the Windows 10 packaged apps stop working even the start menu (Cortana) doesn’t work and the Edge browser does not appear on the taskbar. In my lab I had newly built Windows 10 Enterprise PC’s that are joined to a domain. I know that this is not a System Center related post but I just spent the good part of 2 hours pulling my hair out over this issue so I thought I better have something to show for it at the end of it all. ![]()
