I'm trying to modify the default cmd window properties (QuickEdit, ScreenBufferSize). No matter where I edit them in the registry when I boot WinPE 2.0 they are gone. I've modified it in users\default\ntuser.dat and windows\system32\config\systemprofile\ntuser.dat under HKCU\Console. Anyone know the actual registry file to edit for the equivalent of HKCU in regedit?

Note: I am modifying them in the WIM, not directly from X:. I know when you reboot X: defaults back to whatever is in your boot.wim

When I need to make changes to the HKCU hive, I use:

reg load HKLM\PE-USR %isosource%\Mount\Windows\system32\config\systemprofile\ntuser.dat

I would take a look at the hive while you have it loaded (before closing up your WIM), and see if you can see where it is in there.
