Microsoft has announced that it intends to fully comply with European Union regulators by giving users the option of picking their web browser. If the initial trial program is successful, Microsoft will need to continue the program for five years. This change comes due to the regulators believing that installing Internet Explorer on all Windows PCs is anti-competitive. This will be done through a ballot screen which will inform users that there are different choices when it comes to web browsers. The user will then be able to choose which browser they wish to install. This functionality will come standard with Windows 7, and will be available for XP and Vista through Windows Update.
