As far as MS altering the code, the states can petition for access to the data on the backups that were stored when the case was started (that code wouldn't be altered).
Oh I agree the browser should be there, but I also totally believe MS has used their monoply in OS's to crush other sides of the software market. In particular I remember the shift to windows killed DRDOS with a bogus error message, the shift to windows95 killed wordperfect because they made sure all the wordperfect products were broken on the final code. This netted them the Windows monoply from their DOS monoply, and netted them their dominance in Office products (their big money maker). Don't get me wrong, word and excel are great products, but making sure the competition crashes on your OS is just dirty pool.
MS should be forced to publish all interface's to their OS's publically. This would include SMB, the stupid Kerbos modifcations they did for active directory, NTFS file specifications, etc. With the ability to create products that can interoperate MS won't be able to leverage their monopoly into other areas. Don't forget the court has already ruled they are a monopoly and that they have abused that monoply, this the remedy phase where we determine how to prevent them from doing it again.
