You can open & manage Local User and Group Management in Windows 11/10 Home using Command Prompt & PowerShell command line interface.

Local User and Group Management snap-in or lusrmgr.msc are one of the features of Windows, which allows admins to manage local users and groups in Windows.

The NAS is a Synology DS415+, with a few shared folders currently set up with local user and group permissions. I'd like to enable some people to access files remotely.
