is it possibly to totally modify windows name with hack so that even nlite before customizing show that name. i know that it's possible from registry but from dlls?
thanks in advance.

Where exactly do you want this "new" name to show? During setup, welcome screen, computer properties??? Please be more specific.

it would be better if all of those could be changed. i'm thinking of a total change. could you give me an answer how to change all of them?

You can use ResHacker and look for msgina.dll, logonui.exe, ntoskernel and a few more that I don't know but I'm sure that someone here will give you the full list of files.

thanks for your help and I hope someone will fill your list. Thanks again
