Windows 7 does work out of box for the average user. It works much better out of box than most distros of Linux. With Windows 7 and even more so with Windows 8, you simply install it and your programs.
Of course, that applies for linux as well. I've reinstalled mint three times: once to try it out, again for a new desktop environment (without bloating up the hard drive which was small at the time), and again for an upgrade, and all three installs were pretty much flawless.
With (most) Linux distros you will have to have another computer on hand to trouble shoot the myriad of problems you encounter with a fresh install. When I used Ubuntu my Ethernet and wireless PCI card did not work.
That (most) falls within the range of every operating system that is not very well known. More times than not, when installing Ubuntu, Linux Mint, Debian or Fedora, you won't have any problems, unless you just happen to be unluckily stuck with a system that doesn't work well with linux. All of the previous can also apply to Windows. Out-of-the-box problems are not unique to Linux.
I'm not asking you to change back, I'm asking you to respect Windows for what it is.
Pretty much the only strong point windows has is gaming, so I'll give you that. Stability too, but because of window's closed-source nature, problems can often be hard to fix.
