How can I use the `schtasks` command to obtain SYSTEM privileges, and what are the OS limitations?

You can create a scheduled task that runs with SYSTEM privileges using `schtasks /Create /TN TestService2 /SC DAILY /ST 00:36 /TR notepad.exe /RU SYSTEM`. This method works on Windows 7 through Windows 10, but the older `at` command is only supported on Windows 7. Remember to delete the task with `schtasks /Delete /TN TestService2 /F` after use. This technique is covered in the service creation section.
