Before I get to the Bible lesson, I wanted to make note for my regular readers that Linux Mint is probably the better path to Linux. In particular, I’m going to recommend the 17.2 Release because it offers the most options for the desktop.
KDE is still the easiest to adapt to for Windows users with no time to play around. You can revisit my instructions for the Kubuntu desktop explorations and it will be pretty much the same — try starting with my chapter 7 (use the blog search widget to find later lessons). The reason is because Mint is Ubuntu all fixed up and less buggy. It’s also missing the goofy politics of Ubuntu. So the 17.x series of Mint is based on Ubuntu 14.04 (LTS) and that makes the Mint series LTS as well.
However, I still recommend that you install the XFCE desktop as the most sane approach if you can make the adjustment. That’s covered in my Debian 8 guide (again, use the blog’s search widget for XFCE). And unless your machine was built for Window 8 or later, I still recommend you run the 32-bit version of Linux. It works quite well and can address as much as 16GB of RAM. Up through early Win8 models, most consumer machines rated at 64-bit were actually 32-bit CPUs with extensions to enable 64-bit, but not really a genuine 64-bit processor from the start.
At any rate, back the last time I messed with Mint, it was no better than Ubuntu and friends, because it was built on that base. These days it appears there is more fine tuning than in the past. While I can’t agree with every single default, Mint is currently about as user-friendly as it gets.
