I've heard OEMs make more money from pre-installing adware/spyware/trialware than what they pay for the Windows license.
You can always decline the EULA and try to get a refund for the bundled Windows license. In Europe it is supposedly easy to get a refund due to a European Union directive on unfair commercial practices: http://no.more.racketware.info/en/europe
