I could be wrong, and I imagine @rpo will let us know, but it looks like his cmd script repeats every hour at the :next line from the bottom line and the cmd window might need to stay open to do so. You could temporarily rem the @echo off line at the top (or delete it) to see the script displayed to know that it's not just blank. The results are also piped to a log file. You can put the portable version folder on your desktop and run it from there if you want. If you have a pre-1809 backup, you could restore and see if the Wrapper Script and Task Scheduler works correctly before doing the reinstall. But you know that.
