A user attempts to install additional software and receives a UAC prompt.

A user account that belongs to the local administrator’s group has the permission to install software on a Windows machine. If a user receives a UAC (user account control) prompt when trying to install software, it means the user does not have enough privileges and needs to enter an administrator’s password or switch to an administrator’s account. Adding the user account to the local administrator’s group can resolve this issue. Configuring Windows Defender Firewall, creating a Microsoft account and disabling the guest account are not related to this issue.
