Hello. I searched google high and low, but couldn't find a way to change the flag logo on the classic theme in Vista. In XP the bmp was in explorer.exe, which in Vista isn't the case. Also the side banner in the classic start menu in XP was also in explorer.exe, here isn't. And another thing i need to find out. In XP msgina.dll contained the bmp which appears in the window when you type winver. In Vista, this file doesn't exists. Can anyone tell me the files that I need to find?
