Troubleshooting Windows Applications 0:00-0:12 In this demonstration, we're going to spend some time talking about how to troubleshootapplications on a Window system. We're going to begin by talking about troubleshooting application shortcuts. Troubleshooting Applications Shortcuts 0:13-3:09 Now application shortcuts allow me to double-click an icon and have the associated application run.Now on the desktop of this Windows system I've created a shortcut for the Notepad application. If I double-click on it Notepad is launched. Now you'll note that the application shortcut is not the application itself, instead it's just a pointer that says "Hey, the application you want to run is located over here." So that's where you need to go Windows operating system, to launch the application being requested and you can tell that by this little arrow right here, that indicates that this is a shortcut. If I hover over this shortcut, it tells me where the associated executable is located. It's located in C:\Windows. Now you can see how an application shortcut is configured by right-clicking on it and going to Properties and when we do we first of all see the name of the executable itself, in this case it is Notepad.exe and then we see the directory path where that executable is located. Now at first glance, you might be a little confused because you see %windr%. You might be thinking where on earth is that in the file system? This is an environment variable. The percent sign at the beginning and the percent sign at the end tells the Windows operating system that the text in between is not literal text, it's not the name of a directory but is instead an environment variable and what Windows needs to do is go out and get the value of that environment variable and then to substitute the value of that environment variable here instead of this text from percent sign to percent sign. Now you can view the values assigned to your environment variables by right-clicking on your Windows icon and clicking on System. Go in to Advanced System Settings and then clicking on environment variables down here and if we scroll down we find an environment variable named windr and we see its value over here which is C:\Windows. So by putting %windr% in the target field it tells Windows that the notepad.exe executable resides in C:\Windows. We use the environment variable here just in case I install Windows in some other directory other than the default, maybe I installed Windows in C:\Windows10 instead of C:\Windows.

    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.

    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.
