Before you read below, this is fixed in version 1.4 of the add-in:

There was a new update 'Office Live Add-in' that we started offering through Microsoft Update recently for Office 2007. We've discovered that if you're not the user on the machine that installed it (e.g. install add-in, another user logs on), have 'Do not show me this message again' checked, click close, then close the application, you still get the popup each time you start Word, Excel, or PowerPoint in Office 2007. No other applications use that add-in so you shouldn't see the problem in other add-ins. I've only confirmed this myself on Windows Vista but in theory this would affect any OS version that has Office 2007 installed with the Office Live Add-in. I have since reported this to the Office Live team.
The add-in can be installed either via Microsoft Update under the Optional Updates section (meaning you have to opt-in, not checked by default), or by downloading from the Microsoft Download Center in the Office Live Update 1.3 package.
You have Office 2007 installed and start Word, Excel, or PowerPoint. You get the message below “Get Started With Office Live”, you have the checkbox “Do not show me this message again” checked and click the Close button. However, each time you start Word, Excel, or PowerPoint after checking that box the message still pops up.

Keeps popping up every time you launch either Word, Excel, or PowerPoint (2007) even though you check ‘Do not show me this message again’
[Title] Office Live Workspace
Get Started With Office Live
Thanks for installing Office live add-in via Microsoft Update. You can now get started using Office Live Workspace.
This Office Live Workspace lets you:
-Access and view documents from almost any computer with a Web browser
-Open and save online documents directly from Word, Excel, and PowerPoint.
[checkbox] Do not show me this message again [buttons] Continue | Close
The add-in was installed under another user account and the OfficeLive registry subkey necessary for that checkbox entry to be logged in the registry is not created for other users. You need to manually create the OfficeLive subkey under HKEY_CURRENT_USER\Software\Microsoft for any user on that computer that wants to suppress that add-in by checking the box. After the OfficeLive subkey is created the appropriate registry entry FirstRunDontShow will be created once Word, Excel, and PowerPoint are started and if the checkbox is selected it will no longer show on subsequent launches of those applications.
The issue can be resolved by adding a base registry key named OfficeLive under the HKEY_CURRENT_USER\Software\Microsoft subkey, once that key has been created the next time you start Word it should create two new DWORD entries (FirstRunCredsDeleted and FirstRunDontShow), both set to 1.
