Hello, @ToddAndMargo.

Thank you for detailing the process of adding commands and citing a program as an example. For safe shutdown, it's best to close the program properly or end the task temporarily.

You can close QuickBooks Desktop (QBDT) in two ways. First, click the X button in the upper right corner, and then it will automatically open the last company file upon relaunch. Second, you can go to the File menu to select Close Company, then go back to File to Exit. This method allows switching company files or users upon reopening.

Alternatively, we can hard stop QuickBooks from the Task Manager to kill the main program task and its related background processes. Here's how to do that:

1. Press CTRL + ALT + DEL, then choose Task Manager.
2. Highlight or right-click QuickBooks, then click End task.
   

Speaking of command, consider using keyboard shortcuts to navigate around QuickBooks more efficiently.

Since your concern also relates to Windows, I recommend contacting Microsoft's customer support for personalized assistance. They can help you troubleshoot the Windows side of the command line, permissions, or system diagnostics.

If you need further help navigating the program, add a response below. We're always here to address them.
