You can do some system examination commands such as
NETSTAT - to show network info, parameters select which kind of info
ICACLS - to show file permissions info, parameters select which kind of info for a file
IPCONFIG - to show connection info, parameters select which kind of info - but be careful with this one because of what it can do.
You could practice an auto-backup system using XCOPY or ROBOCOPY, both of which are on Win11. They can be used to build a selective copy script that would let you play with scripting, and if you use a variable save-target such as a thumb drive that plugs into ANY USB port, that would gave you a seriously useful "toy" from a script.
Just get into the CMD prompt and type HELP to see the commands recognized by the CMD processor. NOTE that some of the commands need to be run as Administrator if they would show information from inside other tasks. Before playing with them, take careful note of the ones that can actually change system settings. But you can do a lot of things from a batch file using CMD-related executables.
There are also command line parameters for Office files, too. Running Access with the /X:macro-name string lets you run Access under control of one of its macros. The only catch there is remembering that the macro MUST end with an Application.Quit so you don't clog up your system with extra idle copies of Access.
