from Black Edition to Standard one

Hey. I have one problem, that pursuits for about two months now. I've upgraded from Vista to Win7 7100 without any problem. Then I tried to update it to 7600 with no luck. Because of some sort of error while the installation. Then I've found so-called 7600 Black Edition and installed it successfully over the 7100. Well..I wish I didn't. Cos the Black in the title of this distributive meant that all graphics were changed to custom ones...And they're of very decent quality...Si the question is how can I change everything (log-on screens, themes, icons, start buttons) back to normal, standard Win7 ones? I tried to changed the welcome\log-on screens with different kinds of utilities, but no luck. I wonder if I can simply copy some files from original 7600 distributive and overwrite that ****ty stuff I have. I know, that the easiest way to do it - reinstall the OS, but after a year of using Vista I have an enormous amount of programmes installed and settings set..That would cost me a lot of time resetting and reinstalling.

Thanks for reading and I hope you have some thoughts about it.:)


Some screens attached (horrible, aren't they?).
