Registry Tweaks

You can edit most settings by opening regedit (start -> regedit),
and navigating to the key HKEY_CURRENT_USER\Software\Google\Google Talk

The "Google/Google Talk" key has several sub-keys that hold different option values:

Accounts: This one has subkeys for each different account that has logged in on the client. These keys have different values that store the username, password and connection options.
Autoupdate: Stores the current version information. When the client checks for updates it compares Google's response with these values. If an update is needed, it will download and update the new version.
Options: This is the most interesting part, where most of the current hacks should be used
Process: Stores the process ID. Probably used by Google Talk to detect if it's already running or not.
