What windows you have?
in xp, you simply right click the desktop and go into properties. then you click appearance tab, and the settings are all right there.
This probably works for older windows versions too.
The option is right in appearance, you have to change the theme color, in appearance. If you have windows and buttons set on windows xp style, you only have green blue and silver, if set on windows classic, there is a bunch of other colours.
and get some kick ass themes over at deviantart.com. You want Visual Styles...nit windows blinds. You could get windows blinds way more option but the free version is just ok...hit me up if you have any questions...
Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
