On PowerShell, run this script to rotate logs after a certain number of days. In this example, we set it to 30 days. Then, run this script to remove log files that exceed a defined size threshold. Here, we set it to 100MB. Additionally, you can also compress logs into a .zip file before being archived or deleted using this script: Use CMD and scheduled tasks for basic log cleanup.
