If you want this script to run each time the machine boots another way would be to add it to the Windows registry. The key in question would be HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run. If you want the job to run once only then add it to the HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce key.

Further info on the registry keys in question is here. To manipulate the Registry via Perl see Win32::TieRegistry

Update: Added link to Microsoft docs and Win32::TieRegistry, and the Runonce registry key information

Hope this helps
