Step 1: Open Command Prompt as Administrator

1. Press Win + X on your keyboard.
2. Select "Windows Terminal (Admin)" from the context menu. This will open a Command Prompt window with administrative privileges.

Step 2: Enable Remote Desktop

In the Command Prompt window, run the following commands:

:: Enable Remote Desktop
reg add "HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Control\\Terminal Server" /v fDenyTSConnections /t REG_DWORD /d 0 /f

:: Allow Remote Desktop through Windows Firewall
netsh advfirewall firewall set rule group="Remote Desktop" new enable=yes

Step 3: Create a Firewall Rule (if needed)

If the "Remote Desktop" rule doesn't exist, create it with the following command:

:: Create a firewall rule to allow RDP traffic
netsh advfirewall firewall add rule name="Remote Desktop" dir=in action=allow protocol=TCP localport=3389

Step 4: Add the User "fcastle" to Allow RDP Access

Replace <username> with the actual username "fcastle" in the following command:

:: Add the user "fcastle" to allow RDP access
net localgroup "Remote Desktop Users" /add fcastle

Step 5: Start the Remote Desktop Service

Start the Remote Desktop Service with the following command:

:: Start the Remote Desktop Service
net start TermService

That's it! RDP should now be enabled on your Windows 10 computer for the user "fcastle." You can access this computer via RDP using the computer's IP address or hostname from another machine, provided you have the necessary credentials (username and password) for the "fcastle" account.
