To each their own. Personally running NT6+ on anything for longer than an hour drives me insane. When I need to access a control panel item for example I have to click through 20 times more than on XP and have to use my brain to figure out which exact link I need to click, since apparently icons are no longer fashionable. It wastes my time I could be using doing something important, maybe you say that one time doesn't make a difference but in a day those times get compounded and it ends up making a difference. XP just works and it works the way a desktop OS is intended to, without the quirks without the bloat.
I don't understand you guys who have gotten used to it, maybe you have forgotten how good an OS was and you accept your NT6+ as optimum... in that case I feel sorry for you, I really do.
I think we're just willing to adapt. I find it quicker to get to most things in win 10, instead of having to click through control panel, then find the item I want, I just click start and type in the first few letters of what I want and bam, it shows up. For example, I frequently have to adjust my odbc datasource settings, so I click start and type od and it's right there. It would take a few more clicks to find it in XP. Or, you can get to it without your hands leaving the keyboard, win, od, enter. 4 key presses in about the same time it'd take me to move my hand from the keyboard to the mouse. Device manager is win, dev, enter. Still quicker than even grabbing my mouse.
Plus, for anything accessed that frequently, you can just short cut it on the start bar and it becomes 2 clicks if you don't want to touch the keyboard.
You just need to learn to adapt, you'll discover new and better things instead of being stuck in the past.
Also, control panel in win10, right click on start, click control panel. Then you can have it set to either categories or individual icons (just like your beloved XP) and with the same amount of clicks.
