You can use WSL (Windows Subsystem Linux) to run a Linux VM on your windows machine alongside any other applications. I would recommend that.
To be able to select the OS on startup is called dual boot. This is more complicated though so you might not want to start there if you don’t know PCs and don’t want to put effort into learning.
A Linux version that finds widespread use is called Ubuntu. You likely want the latest stable version.
That wink was somewhat intended ;) The graphs are the intended primary meaning, but Linux usability has actually been complicated in the past.
I.e. I was unable to get a crappy 300$ Laptop running with Linux as a student (ca. 2016) to be used as a youtube/Netflix machine. But that is way in the past. It worked barely when using Windows and I had the hope to prolong its life with Linux. There were some complicated graphic driver issues.
Windows and even Mac are clearly superior. As shown in the graph eventhough Linux is getting better it never even got close.
You ate wrong. It is incredibly useful if the thing you are trying to Google has multiple meanings, e.g. how to kill a child. LLMs can help you figure out more specific search terms and where to look.
