Internet seach engines

[Swimmer]

I have been using Explorer forever. What do I have to do, or what can I do to better sync with Xfinity which is my internet provider? Is it more prudent to somehow just use Xfinity if possble or no? I am continually having problems with Xfinity and I am trying to streamline everything to do with this computor. I am using an early version of Vista. Would it be prudent to just update the computor I have or what? I am at a loss here. I am getting cut off, not being able to read entire articles from different newspapers I look at, because the script is too long, which the window that pops up at the bottom of the screen always says.
