TightVNC Viewer "Server:port" Configuration

When connecting to multiple servers using TightVNC Viewer, it's easy to mistype a server name or port–especially when you're in a rush or juggling multiple remote sessions. And just like UltraVNC, TightVNC remembers every entry you make. That includes typos, outdated addresses, and yes, even passwords if you've saved them. The viewer history becomes a cluttered mess over time.

Fortunately, TightVNC is just as transparent under the hood. After some digging, I found where it stores its connection history–and better yet, how to clean it up.

Where TightVNC Stores Server History

TightVNC keeps its configuration data in the Windows Registry. Specifically, the server list and viewer settings are stored under:

HKEY_CURRENT_USER\Software\TightVNC\Viewer

You can access it via Registration Editor (regedit.exe). Once inside the "Viewer" key, you'll find entries like:

Server
Password
UseRegistry

These can be edited or deleted to clear out unwanted history. Just be cautious--editing the registry can affect how TightVNC behaves, so back up the key before making changes.

Cleaning Up the Mess

To remove old or incorrect server entries:

Open regedit.exe.
Navigate to "HKEY_CURRENT_USER\Software\TightVNC\Viewer".
Right-click and delete any outdated or incorrect values.
Restart TightVNC Viewer to confirm the changes.

If you've saved passwords and want to clear those too, look for the "Password" value. It's encrypted, but deleting it will force TightVNC to prompt you again next time.

Pro Tip

If you prefer not to edit the Windows registry, TightVNC also supports command-line parameters and configuration files for launching sessions. This can help you avoid relying on saved history altogether.

Title: UltraVNC Viewer "Server:port" Configuration
Weblog: GearHack
Excerpt: Connecting to multiple servers using the UltraVNC Viewer, there are many times I fat-finger a server name. And UltraVNC Viewer would remember that in the history, never clearing it out. Worse, if I type in a password in there, it's on the record forever. Luckily, I figured out where the server list . . .
