01
Run the same file on both PCs
Download YAVViewer.exe on both Windows PCs and open it. Choose Host on the PC being controlled, and Viewer on the PC you are using.
Free basic beta · 1.0.0-beta.1
Connect two PCs in three steps.
Both computers need the same build and a network path between them.
Start a session
Keep the generated code private.
02
Start sharing on the host
Keep the host desktop signed in and unlocked. Click Start sharing this PC and wait for the listening status. Give the viewer the host IP address and generated 12-character code.
03
Connect from the viewer
Enter the host address, port 7900 and secret code, then click Connect. Click inside the remote screen to control it. Stop sharing on the host ends access.
Before you start
Use machines you own or have permission to control.
On both PCs
Windows 10 or 11, 64-bit. The portable executable bundles Python and its libraries; no separate runtime is needed.
Host permissions
Screen capture and input operate on the signed-in desktop. Elevated apps, UAC prompts and lock screens are outside this beta’s supported scope.
Choose a connection route
There is no central relay or device-ID service.
Same LAN
Use the host’s local IP address. Allow the app on the appropriate trusted network when Windows Firewall prompts.
VPN
Use addresses reachable through a VPN you already manage. Verify connectivity between the two machines first.
Port forwarding
If you manage the host router, forward TCP 7900 to the host and use its public address. Keep the generated random code; stop sharing when finished.
Troubleshooting
Check that Host says it is listening, the address and port are correct, and both PCs use the same build. Use Check this PC to save a diagnostic report.
Release control at any time
Return to your keyboard
Press Ctrl+Alt+Shift+F12 or click another local window. Click the remote screen to capture input again.
End the session
Close the viewer, or click Stop sharing on the host. Held remote keys and mouse buttons are released on disconnect.
Start with two PCs you trust.
Download the free basic beta. Keep both desktops signed in and use the host’s generated code.
