It's incredibly hard to teach the skill of troubleshooting. You can teach a list of procedure to go through. But you can't teach this almost horse whisperer type ability that some people have when it comes to troubleshooting a computer. When I troubleshoot something I poke and prod some places that I think makes sense and if it's an unfamiliar computer to me I'll do some basic getting a lay of the land kind of information gathering about how the computer feels and then usually my brain makes a connection with a previous case or scenario and usually it's something completely out of the blue that ends up being the exact right thing to do in order to fix an issue. You could say that you can't teach experience I guess. You can't teach sitting at a computer for hours a day for years in a life breaking and fixing your own computer over and over through mistakes or misuse or even on purpose trying experimental things. Like one example that comes off the top of my head was fixing one of my friends computers who was having trouble starting up OBS to stream with. Every single time they would start up obs and they would try and add a video capture device OBS would freeze. I got them to diagnose the chipset drivers and the USB ports and even unplugging everything that was unnecessary to no avail. And then I remembered something from when I was testing a whole bunch of different vtuber softwares, if you don't know what that is it's software to control a 3D or 2D Avatar basically and a lot of them install virtual webcam drivers in Windows. Even if you uninstall them sometimes they don't totally clean up their virtual webcam drivers. So I quickly did a little Google search to find out the registry location that contains all of the current and previously known Windows imaging devices. I found that and then I talked my friend through finding that in regedit and I asked them to click on all of the different entries in there and sure enough those were different webcams that didn't need to exist anymore so I had them delete all of those keys and then reboot and try doing it again in obs and it worked! In fact a lot of things worked better that didn't make any sense at all and I believe that's because a lot of programs in the background or related to obs... Something was trying to enumerate all of the windows imaging devices over and over and over and over and failing. I think if I didn't have that previous experience stored away in my brain that I never would have found out the root cause of the problem and fixed it. Another troubleshooter might have just been like, just reinstall Windows it's because Windows is broken windows broke itself... But that would be completely incorrect. It was poorly built programs not knowing how to uninstall themselves correctly and windows was just fine.
