Hi
I recommend that you give Classic Shell a try.
It's a free program that will make Windows 8 look and work pretty much the same as Windows 7 or XP if you want it to.
I've used it since Windows 7 came out, (I didn't like the scrolling programs menu) it's trouble free, (sorry Trouble no slight intended) and works great.
I'd go crazy if I had to only use the Metro interface all the time.
Your computer will boot directly to the Windows Desktop, it will open multiple windows and have a task bar and all the stuff you are used to.
You can turn it on and off at any time and you can still access the Metro screen with the corner areas or the Windows button, if you want to (I almost never do) and you can get back to doing things on your computer instead of trying to figure out how you get to it.

You might also be interested in Modern Mix which will let the Metro interface open multiple screens and have expand and close buttons in the corner like a normal windows.

This is my Windows 8 boot screen.
Also take a look at Rocket Dock, the bar above the task bar, that lets me access all me commonly used software and folders with one click. Also free!

There is also a way to get the old FreeCell (I'm a addict) and other games in Windows 8, I'll look it up when I get back into Windows.

Ps. I'm messing around and have added this message while booted into Ubuntu, running on a flash drive. It seems to work great, at least it gives you access to your computer in an emergency.
