Holy cow, I wrote a book!
When your program displays a dialog box with buttons, please make the buttons match
the text. Consider this dialog, which appears after you install patches from Windows
It asks a yes/no question, but the options are "OK" and "Cancel". Either the buttons
should be changed to "Yes" and "No", or the text of the message should be changed
to match the OK/Cancel buttons. In the latter case, the text could go something like,
"Windows Update will restart your computer. If you want to restart later, or close
other programs first, click Cancel, and then restart your computer manually."
