Could we update the Task Scheduler guide to start a Command Prompt with the command directly, instead of running a batch file? The current batch script is quite short, so it could easily be executed inline.

For example, something like:
cmd /c "net stop && net start"

Embedding the command this way avoids the need to distribute a .bat file, which can introduce unnecessary security concerns and distribution overhead.
