Even though, majority of OSes force some kind of security measures by default, therefore, in the end, I guess it does take a decommissioned OS and some severely unupdated software to actually bring hazard.
I have lately spent some chunk of my spare time configuring the virtual Windows 10. Long time no see, Windows. Brings a tear to my eye. Memories. I realized though how much people relay on having become used to things. It is all about expectations and custom. It could by why I stick with Linux Lite and disliked GNOME Ubuntu back in the day. It was just too much different.
To make things clear, I also did take my time customizing Linux Lite, which runs native on the hardware.

We talk about the world of cloud services, to be understood. Upgrading should come comparably swiftly as well.
