Hi
Download and install "Classic Shell".

Set the preferences to Boot to Desktop, and you will seldom see the Metro Interface again.
I've been running Classic Shell since Windows 7 came out, (I prefer the Windows XP interface with the multiple program windows).
But you can set it to run just like Windows 7 if you want to.
I use Rocket Dock to access all of my commonly used software.

This puts every thing I use on a regular basis one click away.
You probably won't have a quarter of the software that I run. LOL
I put things that I want to have access to when I have software open (like Skype, File Manger, my Search program Agent Ransack, Word, Chrome, Snipping Tool etc.) on the normal task bar.
This is the way my computer looks at login.

I almost never go to the Metro screen for anything.
As I said I've used it for years and I've never had it cause any issues at all.
I install it on every new computer I set up for friends who are seeing Windows 8 for the first time.

Ps. You may also want to run "Modern Mix" an application that adds the windows functions to Widows 8 applications and lets you see more then one open window at a time.
It does cost $5 though, the others are free.
