For each option: why learners choose it and why it is or isn't the right answer here.

  System Properties > Remote tab

  Why this is correct

  The Remote tab in System Properties (accessible via sysdm.cpl) is the singular GUI location for enabling the Remote Desktop host service on a Windows 10 Pro workstation. It toggles the fDenyTSConnections registry value (under HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server) to allow RDP connections, and it also configures the Windows Defender Firewall rule for TCP port 3389. The 'Select Users' button lets you explicitly grant access to non-administrator accounts by adding them to the Remote Desktop Users group, which is required because RDP connections are denied by default unless a user is an admin or is a member of that group.

  Network and Sharing Center > Advanced sharing settings

  Why it's wrong here

  Network and Sharing Center > Advanced sharing settings is purely a network profile configuration tool. It toggles network discovery, file and printer sharing, public folder sharing, and media streaming for each network profile (Private, Guest, Public). Remote Desktop is a system service—TermService—that listens on TCP 3389, and its enablement is governed by the Terminal Server settings in the System Properties Remote tab, not by the SMB/CIFS sharing stack. While a firewall rule for port 3389 may be needed, enabling file sharing here does not affect the Remote Desktop listener, and this location provides no interface for adding users to the Remote Desktop Users group.

• ✗

  Devices and Printers

  Why it's wrong here

  Devices and Printers is a Shell namespace that manages physical and virtual hardware devices, including printers, scanners, mice, and Bluetooth peripherals. It exposes Device Stage pages and printer queues, and it provides drivers and management options for those devices. Remote Desktop is an operating system feature (the RDP server) that requires the Remote Desktop Services service and the RDP-Tcp listener, not a hardware device or peripheral. There is no functional path from Devices and Printers to enabling Remote Desktop; attempting to enable RDP through this interface would be nonsensical because it controls device drivers and physical I/O, not remote access protocols.

• ✗

  User Accounts > Manage your credentials

  Why it's wrong here

  User Accounts > Manage your credentials opens Credential Manager, a vault that stores sign-in information such as passwords, certificates, and Windows Live credentials for use in network shares, mapped drives, and websites. It is used for authenticating the current user to external resources, not for enabling an inbound remote management service. Remote Desktop enablement is a machine-level configuration that starts the TermService and sets a 'fDenyTSConnections' value to 0; user authorization for RDP is controlled by membership in the Remote Desktop Users group via System Properties, not by storing credentials in the vault. Even if valid credentials are stored in Credential Manager, that does not grant remote access unless the RDP host is explicitly enabled and the user is authorized.
