All of the device drivers for additional devices connected to the system are not loaded, all unnecessary services are also not loaded. This gives us the option to have a bare-bones system that we can go in and troubleshoot. This is a very useful option, for example, to troubleshoot a buggy driver, or to remove malware from the system. Let's go ahead and boot into Safe Mode by pressing 4.Notice that in Safe Mode we're still prompted to login, I'll login as my TestOut student user. Alright, so the system is now booted into Safe Mode, I know it's in Safe Mode because it says in all the corners here, Safe Mode. You'll notice that the computing environment is very different in Safe Mode than it is in traditional mode. That's because only a minimal set of drivers has been loaded and we're using a very basic video driver here, just enough to get a display on the screen. All of the graphical features that we normally associate with the Windows desktop environment have been disabled in order to increase the likelihood of successfully booting into the system. For example, if we were having video driver problems, we may not be able to boot the full system up, so by booting into Safe Mode we don't loadthe video driver that's causing problems, we can go in and then fix it, such as installing an updated version of that video driver. After we reboot the system back into Normal Mode, then everything should work properly. We could also use this mode as we talked about earlier to run an anti-malware scan and remove a piece of malware from the system. Sometimes, it's not possible to remove a piece of malware because its process is running on the system when it's running in Normal Mode. In Safe Mode, hopefully that process doesn't get loaded and so we can actually go in and remove the malware from the system.So, what I'm going to do now is get out of Safe Mode. To do this, I'm going to boot back into Normal Mode, and then I'll use my Settings app to redisplay the Advanced Boot menu. Now I'm going to pause the recording while I do all this, we'll come back once we reach the Advanced Startup menu again. Essentially, Safe Mode gives you the option of getting a very minimal Windows system up and running so you can fix whatever is causing the problem to not run properly. Now, you'll notice here in the Startup Settings menu that there are actually three different versions of Safe Mode that you can choose from. We have the regular version of Safe Mode, option four, that we already looked at, but note that if you use option four, Enable Safe Mode, you will not have a network connection because the driver for your network board will not be loaded. There may be times when you do need to enter the Safe Mode environment, but also have networking enabled, so maybe you could download a driver, or something like that. If this is the case, then you may want to use option five instead, which will also enable Safe Mode just like option fourdid, but also load the network driver and the IP stack for that network board, so that you can communicate on the network. There's another

    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.
