Hi, Grampa Bob.
(I'm a Grampa, too, and my first name is Robert, so...am I talking to
myself? <g> )
A couple of ways to change Open With both involve Folder Options. The
simplest, I guess, is just to right-click on the item you want to open.
Then, on the context menu, hover over Open With, then on the "fly-out" menu,
click the bottom line, "Choose program...". This should open the Folder
Options | Open With screen, from which you can choose the program you want
to use. Note that you can Browse... if your choice is not shown. Also, you
can check the "Always use..." box so that you don't have to go through this
process each time you want to open this kind of file.
The other way to get there is to click Start | Control Panel | Folder
Options, then the File Types tab. Click the extension that you want to
change. In the lower part of this screen, you can click Change to get to
the same Open With box as above. Or click Advanced to get some more
technical customization tools.
