需要用USB 或者光盘启动后，手工拷贝注册表文件

因为我的vista无法启动

I'd like to ask if you could find the location of the registry file in the windows OS.
YES!
Or you have to launch Registry Workshop to restore the registry file?
NO!
Or you could restore the registry file manually?
YES, I did it manually after the bootable XP PE started.

如果系统（如我的vista）可以正常启动，那就可以用registry workshop恢复注册表。
