From Monday, June 30 onwards, the Microsoft Corporation is going to stop selling the Windows XP operating system to the retailers as well as the computer manufacturers irrespective of objections from a group of PC users who do not want to be persuaded into using Vista, the successor of XP. After all the PCs having Windows XP loaded on it get removed from the stock of computer manufacturers like Dell Inc. and Hewlett-Packard Co., those users who cannot do without the old operating system on their new machines will have to purchase Vista Ultimate and then legally ‘downgrade’ it to XP. Microsoft, however, is still going to permit small PC building units to purchase XP for resale throughout the end of January. The XP will also be used in some ultra-cheap PCs such as Asus Eee PC. During the week that passed by, Microsoft stated that it will give complete technical support for XP through 2009 and restricted support through 2014.
