I bought this computer because I needed a computer for work & gaming offline. For some reason, Microsoft has designed Windows 10 so that the computer will not boot up unless the computer is connected to the internet. In addition, Windows 10 will not allow you to run older computer games or most other types of older software. For me, I already have a computer connected to the internet & I did not need another for that purpose. Also, when connecting to the internet, one is subjecting the computer to viruses & malware both of which I have had to deal with numerous times in the past. If you need a computer for work offline & for offline entertainment like gaming, esp. older games, Windows 10 will not work for you.
