The other main difference it that the EU is punishing Google, while turning a blind eye to Microsoft's behavior. They were only fined for bundling IE and WMP with their OS. Locking customers out of competing operating systems is much more harmful in my opinion. The only EU mention of Windows bundling I can find is an Italian court ordering that customers should be able to get a refund for the Windows tax.

Not in disbelief, but could you link me to a source detailing this bribery?

Also Chrome. Chrome was the biggest shocker to many @ Goog. Even as a Noogler, people often sit down in cafeteria and talked about how Chrome got traction and so popular only because it got a main spot on Google's homepage; something noone, no company or individual advertiser can ever bid for. If that's not Google's "Microsoft Internet Explorer anti-trust" moment, then nothing is.
