When Internet Explorer 8 runs for the first time or when we reset the Internet Explorer Settings, you’ll see the Set Up Windows Internet Explorer 8 screen asking for the configuration of the search and accelerator settings.

After configuring the settings, a new tab window opens automatically, redirecting to Microsoft IE8 Website.

The setup modifies the following registry keys under HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main

1. REG_DWORD IE8RunOnceLastShown from 0 to 1

2. REG_DWORD IE8RunOncePerInstallCompleted from 0 to 1

3. REG_DWORD IE8TourNoShow from 0 to 1

4. REG_BINARY IE8RunOnceCompletionTime

5. REG_BINARY Window_Placement

It adds a REG_BINARY key called IE8RunOnceLastShown_TIMESTAMP.

You can disable it as follows:

Disabling the setting on the local machine directly.

a) Open Registry editor (regedit.exe) and navigate to the following key HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Int ernet Explorer\Main

b) Create a new REG_DWORD value named DisableFirstRunCustomize

c) Set its value data to 1.

d) Exit the Registry Editor.

You can also use the Group Policy Management Console to create this particular registry key and populate it to all clients. Read more on this at MSDN.
