There is a registry setting which will tell Internet Explorer whether the runonce page has been shown and completed or not. If it has been shown and completed, this page will never be loaded again. If not, it will annoy the hell outta you! To bypass runonce page, edit the following registry values by following the steps below.

1. Click Start, click Run, type regedit, and then click OK.
2. Locate the following registry subkey, and then click it:
HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main
3. In the details pane, double-click the RunOnceHasShown registry entry and enter 1 in the value data box. Click OK.
4. In the details pane, double-click the RunOnceComplete registry entry and enter 1 in the value data box. Click OK.

Both values RunOnceHasShown and RunOnceComplete value must be set to 1. If any one is 0, the runonce page will start loading again whenever you launch Internet Explorer. Ok, that’s the hard way. The easy way to fix this runonce problem without launching and editing the Windows Registry (regedit) is to use a small tool which automatically does this for you. Simply download and run IE7 Runonce Remover. Click the Remove button and that’s it! You can also use this tool to undo the registry and bring back the RunOnce page.
