Microsoft MUST be FORCED to adopt this policy Worldwide. I am in Australia, and never use internet explorer for anything other than to check for MS updates, it would be far better to be able to use my preferred browser Firefox.
I have a Firefox extension called 'Windiz', available from; http://windizupdate.com/
However, this only checks for windows updates and does not check for MS office updates, but it does help me from having to use the insecure internet explorer, most of the time.
"As agreed with the European Commission to address competition law issues, Microsoft will distribute a Browser Choice Update to users of Windows in EU countries. Starting in March, the update will be distributed to customers via Windows Update. With this update, customers in the affected countries will be presented with a choice of Internet browsers to select from."
It's identified as Update for Windows (KB976002), and will only be installed for users in the EU and 5 adjoining countries. After this update the Browserchoice.exe program may run automatically once to tell about the existence of Firefox, Chrome, Opera and Safari (and 7 others on the next screen), and offering to download and install one of those to replace Internet Explorer as your default browser. For Windows 7 users at that moment it has already unpinned Internet Explorer from the taskbar; it will show instruction on how to pin it back.
If you have any questions about the program, either now or when it has run already, use this thread.
