can't change the default page of IE ?

Its really annoying but most of the IE toolbars (including Yahoo, Google, and ofcourse MSN) change the IE default page to their page and disable any changes to that. I call this ridiculous and anti-marketing for their product. I hated this as much as you do. Funny thing is that IE spits Javascript errors in MSN homepage itself.
So, if you want to remove this restriction do the following :

- Click start and Run ' regedit'
- In Registry Editor, locate the following subkey, if it exists:

HKEY_CURRENT_USER\Software\Policies\Microsoft\Internet Explorer\Control Panel
- if the ResetWebSettings value or the HomePage value exists in this key, right-click the
values, and then click Delete.
- Restart IE and you will be able to change the default page.
