The change has been forced on the software giant following its long running legal battle with technology firm Eolas.

In 2003, Eolas won a historical $520 million (plus interest) court case, which established that it owns the patent on self-executing applets on a web page.

The changes only apply to operations that require no interaction. So, for example, if a website were to automatically open Window Media Player to play some music on opening that is fine. However, if a music file is loaded, Media Player would have to be 'switched on' before it could play the tune.
