Google Talk Hacks

You can edit most settings by opening regedit and by selecting HKEY_CURRENT_USER/Software/Google/Google Talk.
Accounts: This one has subkeys for different accounts that has logged in on the your PC. These keys have different values that store the username, password and connection options.
Options: This is the most interesting part of GTalk, where most of the current hacks should be used.


1. HKEY_CURRENT_USER\Software\Google\Google Talk\Options\show_pin If "1", shows a "pin" next to the minimize button that keeps the windows on top of all the other open windows when clicked.

2. HKEY_CURRENT_USER\Software\Google\Google Talk\Options\view_show_taskbutton If "0", hides the taskbar button, and leaves the tray icon only, when the window is shown

3. HKEY_CURRENT_USER\Software\Google\Google Talk\Options\away_inactive If "1", status will be set as Away after the specified number of MINUTES.

4. HKEY_CURRENT_USER\Software\Google\Google Talk\Options\away_screensaver If "1", status will be set as Away after the specified number of MINUTES.

5. HKEY_CURRENT_USER\Software\Google\Google Talk\Options\inactive_minutes Number of inactive MINUTES to become away if auto-away is on.

Use multiple-identities with GTalk:

1. Right-click on the desktop

2. Select New

3. Select Shortcut

4. Paste this into the text box: ("C:\Program Files\Google\Google Talk\googletalk.exe" /nomutex )
5. Click Next and choose a shortcut name like "GTalk New Instance".

Here you go.... try to execute this newly created short-cut and use your alternate GTalk ID.

/nomutex, which allows you to run more than one instance of GT.
/autostart, when Google Talk is run with this parameter, it will check the registry settings to see if it needs to be started or not. If the "Start automatically with Windows" option is unchecked, it won't start.
/forcestart, same as /autostart, but forces it to start no matter what option was set.
/S upgrade, Used when upgrading Google Talk
/register: registers Google Talk in the registry, includig the GMail Compose method.
/checkupdate: check for newer versions
/plaintextauth: uses plain authentication mechanism instead then Google's GAIA mechanism. Used for testing the plain method on Google's servers.
/nogaiaauth: disables GAIA authentication method. The same as above.
/factoryreset: set settings back to default.
/gaiaserver domain.com: uses a different GAIA server to connect to Google Talk. Used for debug purposes only, there are no other known GAIA servers.
/mailto emailid@domain.com: send an email with Gmail
/diag: start Google Talk in diagnostic mode
/log: probably has something to do with the diagnostic logging

To add these, open up your GTalk shortcut, and where it says "Target:" add one or more of these inside the quotations, but after the .exe part
