Enable RDP Using Remote Registry

You can enable Remote Desktop on a remote computer using Registry Editor. This requires:

• The remote computer must be accessible over the network;
• You must know the credentials of an account with local administrator permissions on the remote computer;
• The Remote Registry service must be running on the remote computer (you can enable it through the services.msc snap-in, GPO, or with the command sc \\RemotePCName start RemoteRegistry).

So, to enable the remote desktop via remote registry, follow these steps:

1. Press the Win + R key combination, type regedit.exe > OK;

        2.- In the Registry Editor select File > Connect Network Registry

   3.- Specify the hostname or IP address of the remote computer. If the remote computer could not authorize you as the current user, you will be prompted to enter credentials;

  4.-The registry of the remote computer will appear in the registry editor (only HKLM and HKEY_Users hives are accessible);

   5.- Go to the following reg key on the remote computer: HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server. Change the value of the fDenyTSConnections parameter (Type=REG_DWORD) from 1 to 0;

  6.- If a firewall is enabled on the remote computer, you must enable the rule that allows remote desktop connections. You can enable it via GPO, via PowerShell Remoting, or using Psexec (check the next sections of this guide).
