going to have to elevate privileges for the installer process that it can make those kinds of changes. So let's see how it works. I'm going to double click on this to start the installation process. I'll accept the terms and the license agreement. And notice down here next to install what do you see? A little shield icon. This indicates that we're going to have to elevate privileges in order to complete the installation process. So at this point user account control is asking whether I want to allow this installer application to install this software on my system. It tells me the name of the program, whether the publisher is verified or not and where the file is coming from. In this case the installer file is located on a hard drive on this same computer. You can come down here and click show details if you want to learn a little bit more about it. For example you can use this option to view the application publisher's certificate. Well, I trust this application. I know it comes from a reliable source so I'm going to click on yes to elevate privileges for the application installer process. This allows it to copy files to the system, it allows it to make registry changes and so on. Now there's an important thing you need to remember about elevating privileges in this manner, and that is the fact that it is a one-time thing. For example if I were to run that same installer file a second time, maybe the first install didn't work out right or whatever something happened, if I were to try to run that installer again the fact that I elevated its privileges previously has no bearing on the second time I launch it. I would have to elevate privileges a second time before it would be allowed to make changes to the system. Another thing to remember is the fact that just because I elevate the privileges of that process, it doesn't necessarily give that process complete and full access to the system. In other words it can't just do whatever it wants to do. It'll only be allowed by UAC to do that one task that it asked permission to do. For example when we installed this application the installer asked for permission to do that one thing, install the application. And that's all it will be allowed to do as an administrative user. If it tries to do anything else it does so as a limited user. So that's how you elevate privileges for a process running on the system if you're currently logged in to the system as an administrative user, and I am I'm currently logged in to this system as the [email protected] user account and it's an administrative user on the system. Standard User 4:43-7:12 Now let's see what happens if we try to perform administrative tasks on the system but when logged in as a non-administrative user. Let's sign out of our current session. And now let's sign back in as the K Sanders user account. Now the K Sanders user is a standard user account. It's a limited user.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
