How do I get web sites and desktop background to use the full scre

We used to have a full screen display of our desktop background and when we
went on the internet we always had a full screen view. Now we only have part
of the screen viewed (leaving the sides empty and everything is in such small
print) How do I fix it to have the full screen view again? HeLp!!!!

 

Windows Mail will remember such a change if you do it by dragging the edges
of its window to the edges of the screen, but not if you do it by clicking
the
maximize button.

 

So how about the desktop image. Why is it in the middle of my screen?

 

Perhaps it's set to be Centered, rather than Fitted?
Right-click on the Desktop, select Personalize
click on Desktop background
at the bottom, click on the first position option.

 

Thanks so much Dave for the help. It worked. I really appreciate it!
