I spent much time before finding that the installed windows has Fonts missed. "RT7-Remove Component" has removed fonts in C:\Windows\Fonts (see here bellow attached files). Moreover, by removing the following fonts DVD\boot\fonts\chs_boot.ttf, cht_boot.ttf, jpn_boot.ttf, kor_boot.ttf and DVD\efi\microsoft\boot\fonts\chs_boot.ttf, cht_boot.ttf, jpn_boot.ttf, kor_boot.ttf ,during the windows install, after the second restart, it black window freezing. I had to reset the computer and Start windows normally to get the Welcome window.
