Default Homepage Settings on Internet Explorer

You can set a registry entry to lock your IE homepage.

1. Go to:
HKEY_CURRENT_USER\Software\Policies\Microsoft\Internet Explorer\Control Panel

2. Create an DWORD entry of Homepage with a value of 1

That should lock it up for you (depending on your OS - though it works for Win2K)

You can also create a new Key under
1. HKEY_CURRENT_USER\Software\Policies\Microsoft\Internet Explorer\Restriction

2. Then under HKEY_CURRENT_USER\Software\Policies\Microsoft\Internet Explorer\Control Panel\Restrictions, create a DWORD value called "NoBrowserOptions" with a value of 1.

That will disallow opening IE options from within IE. (You'll have to go to the Control Panel to set IE options after that.)
