As you can see by the image below, my menu bar titles at the top are small and blurry, plus anywhere there is a text field box (i.e. length & width text fields in the Image Size window) it is collapsed vertically and therefore I can't see what my values are. You can also see the 3 checkmark boxes at the bottom of the Image Size window are cut off. I previously had CS6 installed on a Window XP machine without any issues. Now that I have "upgraded" to Window 7, this is what I get for results after the install.
Straighten out your system's fonts. All those menu entries and palettes use the wrong font eitehr because you removed the right one (Trebuchet, Verdana), it is blocked or has some otehr problem. Also update your graphics driver.
