this interface. Now that being said as you go through this list of services you probably won't recognize very many of these, you won't know whether it's necessary or not. So be very careful before you go through hereand start disabling services. Before you do that, go ahead and go on the Internet, Google the name of that service and find out what it is, what it does and if it's necessary for the system to run or not. Summary 6:04-6:18 That's it for this demonstration. In this demo we talked about troubleshooting services on a Linux system. We talked about what a service is, we talked about how to use the Services desktop app to troubleshoot services. We talked about how to use Task Manager to troubleshoot services and we talked about how to optimize services using the system configuration utility. When troubleshooting applications, it is always best to check a knowledge base on the manufacturer's website or search on the Internet for an answer to the problem first. The following table contains guidelines for troubleshooting common application issues: Problem Troubleshooting Method Shortcut malfunction Installation of an application may create a shortcut on the desktop. The shortcut is a pointer file that identifies the location of the executable file that runs the application. During install you can often choose to add shortcuts for only the current user or all users. Shortcuts will cease to work if the file to which they point is moved or altered, or if a drive has been remapped to a different drive letter (which can happen when working with removable media). Some issues can be resolved by fixing the shortcut instead of re-installing the application. Edit the properties of the shortcut to correct many application-related issues: o Use the Target field to point to the executable location. o Use the Start in field to identify a working directory for the application. Installation issues Application installation involves more than just copying the executable files to the computer. Installation typically modifies the registry, creates shortcuts, creates Start menu tiles, and configures other settings required by the application. Users must have the appropriate permissions to install applications. The ability to install applications depends on the user's group membership and the operating system: Users who are members of just the Users group are not allowed to install applications. On older versions of Windows, users who were members of the Power Users group could install applications as long as the installer did not modify system files. On modern versions of Windows, Power Users cannot install applications at all. Users who are members of the Administrators group can install applications. If an application's files get deleted or become corrupted after installation, they can be repaired by doing one of the following: Some applications provide the Repair option in Programs and Features. When selected, the Repair option inspects all of the application's files and replaces files that are missing or corrupt.

    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.
