Frequently asked questions (FAQs) about this topic

What is RealVNC Viewer used for on Windows?

It is used to connect to another computer and see its desktop remotely. That makes it useful for IT support, home troubleshooting, and managing unattended PCs. You can usually control the remote mouse and keyboard if permissions allow it.

Do I need software on both computers for VNC remote access?

Yes, remote access normally requires a viewer on the local PC and a server or host component on the remote machine. The host must be configured to accept incoming connections. Without that side running, the viewer cannot connect.

Is VNC secure for remote desktop connections?

VNC can be secure when it uses strong authentication and encrypted connections. Security depends on how the host is configured and whether you expose it directly to the internet. A VPN or other protected network path adds an extra layer of safety.

Can I use VNC to control a computer without someone there?

Yes, many VNC setups support unattended access. That is common for home servers, office workstations, and remote maintenance. You usually need to set a password and enable the right access permissions on the host.
