For Windows CE, "boot time" is a bit ambiguous. When a user presses
the "on" button, the unit really just wakes up; programs _can_ detect
this event. A "warm reboot" is closer to "reboot" on "big" Windows.
Any program with a link in the Startup folder will restart after a
"warm reboot".
I _think_ programs can monitor this signal. I don't think the
operating system does anything by itself.
Many choices. For more info, see Chris De Herra's list:

or use google to look up my posts on rugged handhelds.
I'm quite sure that no handheld running Windows CE every turns off
completely. That means they all drain their batteries when sitting.
Some in 2-3 days. Some in 2-3 weeks. And when their batteries drain,
they lose all data stored in RAM, so they are essentially restored to
"factory new" when turned back on. In particular, all installed
programs and data are lost.
Some Windows CE handhelds provide mechanisms to store CAB files in
ROM, so programs can be reinstalled automatically on cold reboot (full
battery drain or special button combination). This feature is more
common among industrial handhelds, like DAP or HHP/Dolphin. At least
one of our VARs uses this technique, but I have been blissfully
unaware of the details.
