Automatically Pausing Scheduled Tasks in Windows

I’m wondering whether it is possible to pause a scheduled task in Windows.

I have a scheduled task that looks for the presence of a file every 30 minutes and then processes the file. (The file appears at various times over the course of about 8 hours and needs to be processed quickly after it appears.)

I’d like to modify the process so that once the file is found and processed, the scheduled task is paused for 8 hours so that it doesn’t needlessly re-look for and re-process the same file every 15 minutes after it was originally processed. The scheduled task would then need to be “active” after that up to 8 hour pause.

Thank you for your time.
