What kind of a program is the Windows 8 "Choose an Option" page?


  • Which .exe file (if any) corresponds to this program?
  • Does it run as a user-mode component or a kernel-mode component?
  • Is it a native NT executable, or does it run under the Win32 subsystem?
  • Does it come up before or after turning on paging?

I think I found it... it seems to be bootux.dll.

It's executing in user-mode indeed -- it's written in C++ and it's using DUI70.dll (the internal DirectUI API), along with other Win32 components.
