Turn it on and connect
Remote control is off by default. Both computers need it turned on in 77Fox and need to be signed in to a 77Fox account; different accounts are fine. It works only between two Windows PCs: the web app, the browser extension and phones can neither control another computer nor be controlled.
Each computer has a fixed 9-character connection code of letters and digits. Change it to something memorable or randomize it; the old code stops working right away, and you can’t change it during a session. To connect, enter the other computer’s code and choose Request access or Password access.
“Copy connection info” copies the code together with any saved password, so send it only to people you’re letting in. When someone sends you that text, copy it and switch back to 77Fox; you’re asked to confirm before anything connects.
Once connected, the viewer lets you switch displays, fit the picture to the window, show it at actual size or go full screen, and change frame rate, resolution and bitrate on the fly.
Request and approve
With Request access, the other computer shows a small call-style window explaining that you’ll control the PC and receive its system audio and microphone. Nothing starts until they click Allow access, and Decline ends it. No screen, audio or input is captured before they agree.
The prompt offers Always allow this device. After that, requests from your device are verified automatically and connect without a prompt; that’s a trusted device. Trust belongs to that one device: another PC on the same account doesn’t inherit it. Only tick it for your own computers.
Trusted devices are listed on the remote control page and can be revoked anytime; revoking asks for confirmation and ends that device’s current session.
Password access
The first time you turn remote control on, 77Fox generates a 10-character random password; you can set your own instead, at least 8 characters long. Enter the right password and you’re connected.
Here’s what that means: with a password or a trusted device, the controlled PC shows no confirmation prompt. The only sign is a small dot on the corner of its tray icon, and its system audio and default microphone are sent across. So give the password only to your own devices or to people you trust.
The password stays masked; reveal it in the main window and it hides again after 30 seconds. “New password” stops the old one from working for new connections without dropping a session in progress. Random passwords can be changed by hand or automatically after each password session. To allow requests only, turn off “Allow password access”.
Quality and audio
Pick Automatic, Smooth, Balanced, Sharp or Custom. Automatic is the default: 30fps, 1080p, 6 Mbps, and Balanced uses the same settings. Smooth uses 720p and 2 Mbps and keeps the frame rate up when bandwidth runs short; Sharp uses 4K and 16 Mbps and holds on to detail instead. Custom sets limits for frame rate (15, 30 or 60), resolution (720p to 4K) and bitrate (1 to 30 Mbps).
Audio is one-way: the controlled PC’s system audio and default microphone come to you, each with its own volume, and your microphone isn’t sent. The person at that PC can switch either one off from the tray menu at any time. If a device can’t be read, you’re told, and the screen keeps streaming.
Each computer accepts one controller at a time, and a request waiting for approval counts as that one.
Page and history
Remote control has its own page: your connection code, password and connect form at the top, replaced by the current session once you’re connected, and History, Trusted devices and Settings tabs below.
History is stored only on this PC and keeps up to 100 entries: device name, who connected to whom, the method, the time and the result. It never stores passwords, screen content or keystrokes, and it isn’t synced or backed up. Computers you’ve connected to get a Reconnect button that sends a fresh request; history never keeps passwords, so it always asks.
Safety: read this first
Scam warning: if anyone claiming to be support staff, your bank or the police asks for your connection code and password, don’t give them. Give the password only to your own devices or people you trust, and turn remote control off when you’re not using it.
Nobody gets in until the PC’s owner turns on remote control in 77Fox and either sets a password or clicks Allow on the spot, and the tray can end the session at any moment. During a session, a small dot sits on the corner of the tray icon, orange while a request waits and green once connected. The right-click menu names the connected device and keeps Disconnect and the audio switches for the whole session. Turning remote control off also ends any session in progress.
Screen, audio and input travel encrypted over WebRTC through relay servers run by 77Fox. The 77Fox server that sets up the connection only passes connection signals and online status, and never receives your password in plain text. Device keys, passwords and the trust list stay on this PC; they aren’t synced or included in backups. The input channel accepts key and mouse actions only, never commands or file access.
What it can’t do
It can’t control the lock screen, the screen before Windows sign-in, the UAC secure desktop (administrator prompts) or Ctrl+Alt+Del. It doesn’t move files between computers or carry over what you copy and paste. To control apps running as administrator, turn on “Administrator windows” on the controlled PC first; Windows asks for approval once when you enable it.
