The first problem is the most strange one.I want to copy some themes into windows folder,so I put "Resources/themes" in "$OEM$/$$" in the ISO.But after the system setup is complete,I just can't find any theme file in "themes" folder on my disk.So,that's what kind of problem? I also wrote a reg file to optimize my system by typing"regedit /s setup.reg" in the cmdlines.txt.But when the system setup is done,I find that some phrases in the reg file does't work. e.g. I want to show protected system files,so I set: [HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced] "ShowSuperHidden"=dword:00000001 But I find that the regedit changed "ShowSuperHidden" into "SuperHidden" and no "ShowSuperHidden" is existed,how could it be possible?In addition,if I double click the reg file directly,it works well. Besides,I also set: [HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\StartPage] "Favorites"=hex:ff "FavoritesResolve"=- to remove IE&OE from start menu.As the same,If I double click the reg file,it works.But it just does't work from cmdlines.txt.After the system setup is complete,"Favorites" isn't changed to "ff" and "FavoritesResolve" doesn't remove yet. I have already turn Windows File Protection off by set HKLM,"SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon","SFCSetting",0x00010001,0xffffff9d in HIVESFT.INF So,what I gonna do to solve these problems?Hope you guys will help me Sorry for my poor English
