Is it possible to call one Windows scheduled task from another Windows scheduled task?

I have created two independent task Windows scheduled task's:

1. First task running under system-context (needs to run under system-context as application needs to be installed silently) checks if already installed application as any updates on every scheduled interval.

2. Second task running user-context (needs to run under user-context because when run under system-context its running in background) which open one pop-up for restart.

I want to call second task which is running under user-context only when there is updates available for the application.

If anyone has suggestions it would be much appreciated

Solution 1:

The first task may start the 2nd, yes. The syntax would simply be

schtasks /run /TN secondtasksname
