Microsoft teamed up with Child Exploitation and Online Protection Centre (CEOP) for a noble cause and has released a customized version of Internet Explorer 9 today as a part of Safer Internet Day 2012.
Basically the customized Internet Explorer 9 offers Thinuknow.co.uk and Bing.com as home pages. Microsoft put some serious efforts with CEOP to build bookmarks and jump list including Windows 7 Taskbar notification. The search bar includes an internet safety search site which provides easy access for children and appropriate information.
