Use the "Scheduled Tasks" activity under the Control Panel in Windows. If you don't see it, that means that your IT group has disabled it and you need to get them to put it back.
You also need to read the SAS documentation on how to run SAS in batch from the command line, you will have to add the parameters that are included in the file association under Windows.
I find it easier to create a Windows batch file (.BAT extension) that includes the SAS command, get that running from the command line, and then add the batch file (or just copy-n-paste if it is just one line) to the scheduled tasks activity.
