Executing a command under the context of that account, whether through a batch file, an application, or SSMS isn't elevating your privileges

Apparently you're not clever enough to submit a 'login' command in a batch script file with Administrator credentials? And then do your dirty work, and end with a deletion of log file entries, followed by a 'logout' command?

Sure - you can authenticate in a batch file with admin credentials...

But if you already have admin credentials, you can just log in with them and do what you want. The batch file isn't giving you any special powers...! Yikes.
