The AppLocker tool allows you to restrict the programs you can run in Microsoft Windows, we have already covered one aspect of this topic here. To sum it up in a nutshell, through the Applocker you specify the rules on your running applications. Now if you want to use the DLL Rule Collection, then you will need to enable them as they are disabled by default.
Click Start, type secpol.msc and press Enter, the Local Security Policy box will be displayed.
Now, expand the Application Control Policies in the left box and right click the AppLocker, then choose the Properties option.
Choose the Advanced tab, and then check the Enable DLL Rule Collection option.
Click Apply to complete the configuration, please note that you should enable DLL rule collection only if you are going to implement them properly otherwise they can effect your system’s performance. Enjoy!
