According to this website Schtasks - Scheduled tasks | SS64.com
I should be able to create or run a task and use /RU to use a system account. The site says "For the system account, /RU username
can be written as "", "NT AUTHORITY\SYSTEM" or "SYSTEM", a Password is not required. The system account has full access to the local machine", yet I always get prompted for UAC approval. It doesn't ask for credentials, but I do have to repond to the prompts. Any assistance will be appreciated. The task writes a key to HKEY_CURRENT_USER when a new profile is created via a RunOnce batch file.
