First login to a Windows VPS managed with Virtualizor

Windows VPS servers on Virtualizor run on KVM and are managed from the same panel as Linux servers. You connect to Windows with Remote Desktop (RDP), and the Virtualizor VNC console is your backup when RDP does not work. This guide gets you from the welcome email to a secured desktop.

Before you start

• Your VPS IP address and Administrator password from the welcome email or the Virtualizor panel.
• A Remote Desktop client: Remote Desktop Connection (built into Windows, mstsc), the Windows App on macOS, or Remmina on Linux.

Find your details in Virtualizor

1. Log in to Virtualizor and open the VPS. See panel overview.
2. Note the main IPv4 address on the overview.
3. If you do not know the password, set a new one under Settings → Change Password (supported on Windows templates with the guest agent) or reinstall the template with a new password.

Connect with Remote Desktop

1. Open Remote Desktop Connection (mstsc).
2. Enter the VPS IP and click Connect.
3. User name: Administrator; password: the one from the panel.
4. Accept the certificate warning on the first connection (the server uses a self-signed certificate).

Under Show Options → Local Resources you can share the clipboard and local drives to copy files.

When RDP does not connect: use VNC

Open the VNC console in Virtualizor. Use the Ctrl+Alt+Del button to reach the login screen. From there you can check whether Windows is still installing updates, whether Remote Desktop is enabled (Settings → System → Remote Desktop) and whether the firewall allows port 3389.

First security steps

1. Change the Administrator password to a long random one.
2. Create a separate admin user and consider disabling or renaming the built-in Administrator account.
3. Run Windows Update until no updates remain, then restart.
4. Keep Network Level Authentication enabled for RDP.
5. Limit RDP in Windows Defender Firewall to your own IP addresses if they are fixed. Find yours with the IP checker.
6. Enable an account lockout policy to slow down password-guessing (secpol.msc → Account Lockout Policy).

Useful Virtualizor actions for Windows

• Restart and Power Off when Windows hangs; see power controls.
• Reinstall OS to start over with a clean Windows template.
• Extend the disk after an upgrade in Disk Management (right-click the C: volume → Extend Volume).

Troubleshooting

• "Remote Desktop can't connect": the VPS is still booting or updating, RDP is disabled, or a firewall blocks port 3389.
• Password rejected: keyboard layout differences; try typing it in VNC first, or reset it from the panel.
• Slow desktop: lower colour depth and disable visual effects in the RDP client's Experience tab.
