Task Scheduler runs as hidden, how to make it visible?

This isn't possible anymore: services are run on a different desktop than users, and this affects the Task Scheduler as well. More info: http://blogs.technet.com/b/askperf/archive/2007/04/27/application-compatibility-session-0-isolation.aspx

What I'd suggest is that the scheduled tasks pipe the output to a log file, e.g. instead of abcd.exe, abcd.exe > c:\logs\abcdlog.txt

I discovered that a task has to be set for "run only when user is logged in" to be visible. Otherwise it is hidden (regardless of the setting of the "Hidden" checkbox).
