I've replaced all of my files that need to be replaced, and put the files that need to be there where they should. I told the winnt.sif to use a certain file for the theme, and all of that good crap. I've tried to install XP twice with this special theme, once with SP1 intergrated, once with SP2 intergrated. The first time, with SP1, everything went smooth until explorer started. It was running in classic theme when it should have been running in the theme I chose. No biggie, I just went into the settings and changed the theme. I intergrated SP2 today, and installed it. Went the same way as SP1, exept now, It won't use the theme. Anyone know how to fix this? Should I replace the file that does the theming with the cracked version again, or should I go back to SP1, or what? I can't seem to figure out what makes it not use my theme on startup. I've got "CustomDefaultThemeFile="advance4-3_normal-black-whiteback.THEME"" under [shell] in winnt.sif, but it won't use the theme. Anyone know what the problem is?
