Solved Not sure of my internet explorer configuration/settings

I'm a newbie to Windows 7 Home Premium & think maybe I've messed up IE9. It seemed to me to be slow & some sites left me with hundreds of items in Temp.IE Files while others, this one in particular, just left 1, so in trying to get less from somewhere else I messed around with IE settings & now don't even remember what I did. So actually I guess my main question is: what is Microsoft Fixit? I've seen reference to it several times but have never used it. I have a very wide 'yellow streak' down my back & don't know which way to go.

Thank you.
oops, forgot to mention that the reason I came here to post was that I'd been in the Tutorials doing some reading when I was interrupted by a phone call & when I came back to continue, it took what seems like forever to 'wake up' my screen. Then when I came back here to edit, it again took too long to open my post. I'm sorry, my wording may be wrong, hope this makes sense.

Regarding IE9 setting changes:

IE has a lot of "Restore Default" options in the settings.
Try going back through the IE Options and setting everything back to "default".
If your OS came with IE8, you should also be able to uninstall/re-install IE9...
