Before we go any further, let's get this out of the way: You should upgrade to Windows 10. If you're using Windows 8, 7, XP, ME, or 3.1, you should upgrade. Maybe wait a couple of weeks for the biggest bugs to be squashed, but do it. Why wouldn't you? It's free, it's easy, and it's a huge improvement on whatever version you're using.
Windows 8 came out in 2012, chock-full of Grand Proclamations About The World. Two-in-one devices are taking over! Touchscreens are great! Old apps are stupid! Who cares about settings menus! Interesting ideas, the lot of 'em. Almost none came true as quickly as Microsoft hoped. To the vast majority of Windows users, stuck on laptops and desktops, its big icons and relentless focus on gestures and full-screen apps felt like a futuristic anachronism, an operating system designed for gadgets that don't exist. So people either resisted upgrading, or regretted it.
The subtle, remarkable feat of Windows 10 is that it manages to introduce equally powerful new ideas without being so overbearing. If you upgrade your laptop from Windows 7 and steadfastly refuse to use any of the new features, the new OS will feel mostly like an aesthetic makeover. The design is cleaner and flatter, with heavier contrast between icons and backgrounds and a slightly darker overall look. It's more consistent, too, as if Microsoft's designers finally made it deep into the menus. But it's the same Windows you've always known. Start Menu and everything.
The Start Menu, actually, is a perfect microcosm of what Windows 10 does well. It's totally familiar to anyone who's ever used Windows before, slotted in the bottom-left corner with its quick shortcuts and list of apps. But off to the right in the menu, there are the ever-flipping Live Tiles with information about the weather, your inbox, and the score of the game. Live Tiles were always a good idea—the problem was that they took over the screen and left you without any sense of your place in the OS. Now, they pop up semi-opaque over whatever you're doing, with a really smart mix of shortcuts and information.
