You can also set up a scheduled job that runs automatically using ElevatedShortcut to clear the event log.

```
wevtutil el > Loglist.txt
```
This creates a text file Loglist.txt in the working directory of the command prompt (the same folder where y'all are currently at the command prompt).
At present that you know the name of the log you want to clear, you can use the following command:
