This first step isn’t mandatory, but it’s a good idea: back up your computer. If you can, make sure that all of your most important files are saved outside of your PC. More than likely you aren’t going to need this, but it’s better to have it in the event that something goes wrong.
Once Windows 10 starts installing, you’re almost set. Depending on how new your computer is, this could take anywhere from 20 minutes to an hour or longer, but there isn’t that much for you to do aside from click “Next” a few times.
Click Next, check off some settings, and you’re basically good to go
Eventually, the Windows 10 installer will ask you to configure some settings. It’ll offer you the option to customize the settings or to choose what Microsoft calls “express settings.” We’d recommend clicking customize — it won’t take more than a couple minutes longer, and there are some options that you may want to change. That includes how Windows handles location privacy, ad tracking, browser settings, and whether or not your computer automatically connects to open hotspots.
Once you’re through that, the installer will finish setting things up and bring you to the desktop. From there, you’re very nearly good to go. You’ll want to run Windows Update one final time to make sure that you aren’t missing any recent updates or drivers specific to your computer. And that’s it — once you’re sure everything’s up to date, you’re good to go: Ask Cortana a question. Stare at the beauty of the Start menu. Annotate something in Edge. And enjoy the rest of the new but familiar world that is Windows 10.
