Microsoft was not fined for integrating IE IIRC. They where fined because they did not allowed you to install Netscape for example.

I meant to said that they prevented OEMs like Dell, Acer, etc., to install Netscape. They gave them more discounts and such if you didn't install Netscape.

They did similar with OS/2 IIRC. Is not that they prevented you from installing OS/2 as an OEM, but Microsoft will charge you for the number of PCs you sold, not he PCs with Windows.

This was a long time ago, so I might be wrong.
