Installing your operating system such as Windows has advanced and changed with every new release they've made. The days of every PC having an Optical Drive installed in them are now in the rear window so there's an easy way of installing Windows 10 on to your new PC. All you need is a blank USB stick, a Windows 10 product key which you can buy online and a small bit of time and patience for the installation.
Visit the official Microsoft website here - https://www.microsoft.com/en-gb/software-download/windows10 , download the file via the blue 'download tool now' button, run the .exe file you download and folow the instructions on how to set up on the drive as outlined in the video below with step by step instructions.
The process of installing the operating system is fairly straight forward, you'll spend a fair amount of time waiting for the installer to run, accepting terms and conditions from Windows and also customizing your set up when choosing tasks such as Keyboard layout, Languages, Cortana settings (off) and more.
In the how to video we also cover some post installation checks we advise doing such as checking for Graphics Cards' drivers and formatting any extra hard drive storage you may have installed.
Once you're all done you can be as happy about your new PC as this.
