I did find that I could go to Dell after upgrading and install the one I lost then update the drivers, at least that is advice from Shane at Tweaking.
However, it has been a learning experience just trying to decide what to do.
Contrary to my compulsive nature, I am glad I did not pull the trigger and will stick with seven.
I can't complain as it does everything I need but I sure would have likes to have played with 8.
I think I shouldd not install new over old but, when necessary, buy new and take what comes with it.
Thank you again and c u soon, as the kids say.
