Silent update isn't working?

[megablue]

how does silent update (/silent /update) works?

I had configured PatchMyPC to trigger whenever I am idle for more than 1 hour at the Task Scheduler. However, i figured some programs still remained outdated even PatchMyPC was triggered.

Do I have to perform the update manually?

It should be able to update any application within Patch My PC when run silent.
