Changing *.exe File I Created To Non-exe Type

I've created a slideshow file, using FastStone Image Viewer 4.3, and pictures I took myself in our back yard. The file is *.exe and self-executes correctly on my computer. I've scanned it with MSE and it's clean and virus-free.I want to send it to our daughter, using my Hotmail account, as a normal attachment to a normal email msg. But Hotmail blocks it completely since it's an executable file type.So I tried to just rename a copy of it on my hard drive, first, to *.txt. But when I select the *.exe filename and then click Rename, I can't seem to get access to the extension part of the current file name; the exe after the dot. So is there a way I can change the file type in windows from "application" to a type Hotmail so windows won't block as an email attachment? Then tell the recipient to change it back to *.exe on her end?
