Khi Val,

Couple of things you could try, first press windows key and X, this brings up a list , the first item should be apps and features, click this then tab to the list of installed programs, scroll through the list to find your program and hit enter on it then press tab, normally the first option is modify , tab again and then the next option Is usually uninstall. If that doesn't work, press the windows key, then press up, then to the right, this brings up a list of programs just keep pressing down until you find the program, press enter on it to expand the folder and there may be an uninstall option in here. I'm not sure, what they mean by system disk, I would think they mean press windows key and E to bring up file explorer , then find your list of drives, you would want the one called either local drive - c drive, or I've seen it called windows drive before too, click this, then go to program files (there will be two one called just program files and one called program files x86) it could be in either of these depending on the program, but you should find the program in one of the lists, you could open the folder and see if this uninstall file is in here. But word of caution , I'm not 100% sure this is what they mean by system disk, although I can't think anything else they would mean, but if your new to windows the local drive holds all your system files so be very careful in here not to delete anything, definitely do not delete the program folder from here as this will not remove it from your PC but may cause you system problems if you do, basically as a general rule never delete anything from this drive as they are all system files. I'd definitely try my first two options first.
