My IE 7 has slowed down since I installed & uninstalled programs in an effort to find something that works on Vista.

My IE's speed is to slow.

I tried System Restore & Sfc /scannow.

If I downloaded IE 7 from the net & installed it, would it over write my
IE 7's errors or mess up my PC?

I really like IE because it works with Site Adviser.

Thanks
