Adrien Ferrand 595b1b212e [Windows] Avoid letsencrypt.log permissions error during scheduled certbot renew task (#7537)
While coding for #7536, I ran into another issue. It appears that Certbot logs generated during the scheduled task execution have wrong permissions that make them almost unusable: they do not have an owner, and their ACL contains nonsense values (non existant accounts name).

The class `logging.handler.RotatingFileHandler` is responsible for these logs, and become mad when it is in a Python process run under a scheduled task owned by `SYSTEM`. This is precisely our case here.

This PR avoids (but not fix) the issue, by changing the owner of the scheduled task from `SYSTEM` to the `Administrators` group, that appears to work fine.

* Use Administrators group instead of SYSTEM to run the certbot renew task
