When I bring up Internet Explorer for the first time, I get a Microsoft sponsored page, a portal to Microsoft Live. My default search provider comes up as Microsoft Live. For me, the easiest way to change home pages is to open up the pages that I want to have as my home page settings, and close the window that Microsoft Live opened.
I navigate to Bright Hub, at www.brighthub.com. Next, I open up a new tab, and go to brighthub.com again. Now, because I am an editor, I have access to the article writing interface, where I do my work. I go to that page after I bring up Bright Hub for the second time, navigating to a channel where I edit, and I click on a link to allow me to Manage Articles. Now, I open a new tab. I type Google in the address bar, and hit the control key and the enter key. This puts in the prefixes and suffix I need for a complete address, and I hit enter to go to the site. Now, I have three pages on separate tabs in the IE7 browser.
Find the home page icon. It is located in the same line as the tabs, over toward the right hand side. It looks like a tiny house, and has a small black triangle next to it, which will bring up the menu for the icon. (At this point, if you click on the icon and not the menu, you will return to the original home page.) On the menu, you will see options to add or change the home page, or remove the current setting. Select 'Add or Change Home Page'. The options are: 'set this webpage as your only home page', 'add this webpage to your home page tabs', 'use the current tab set as your home page'. Select the one that you want. You can also click on the menu on the home page icon to use the Remove option. Highlight a page, if you have several currently selected, or select 'remove all'. This brings up a dialog which asks if you are sure. If you select 'remove all', your home page will be a blank window.
