There is no option in the settings to turn this off.

I can't find where Fotosketcher knows what version to get in taskschd.msc.
Fotosketcher Program Files has only fotosketcher.exe and unins000.exe.

Where does home dialing come from?
Is it hard code?
How can it be stopped?

You could block it that way.

The HOSTS file wouldn't be enough, if the program
is using a fixed IP (numeric) address.

You can try out the firewall method and tell us
whether it works or not. It's going to be blocked on
outbound.

A program does not have to "tolerate" being blocked.
Once a program is within your "perimeter", there
are a ton of things it can do. The above web page
is intended for "moderately aggressive" programs.

A program which is "maximally aggressive", I think
it would really be hard to stop. For example, it
could launch separate randomly named attack EXEs
to send messages. A program doesn't have to
"stay within its EXE". A tool like the old ZoneAlarm,
would stop "new" programs and prompt you for a policy,
but this would be annoying if every time you ran the
program, ZoneAlarm was prompting you again. And if the
attack EXE was named "Notepad", ZoneAlarm might mistake
a newly launched program, for an existing program.
