Windows Mobile Startup Hack

I would love to investigate how the windows mobile registry can be
hacked to prevent the welcome screen, align screen,stylus tutorial,
location, complete screen and HP IPAQ Experience. I have found a few
files called Windows\Setup.exe Windows\welcome.exe.

I have the registry viewer for the PPC ARM. But no idea how to
change a key value.

Then you can issue from your pc synce-prun "SD Card/haret-0.3.6.exe" and
boot straight into linux without all the lame ms crap.

Any ideas here?
