Is Microsoft Reverting Back to XP from Vista?

Are the computer ads by Apple Inc. (AAPL), which trades on NASDAQ, correct? Is Microsoft (MSFT), which also trades on NASDAQ, now maintaining support for Windows XP, which it was formerly trying to wean people off of? Many businesses and consumers have decided not to upgrade, for compatibility purposes, for learning curve purposes, and for time and expense purposes. Apparently, Microsoft has decided that they will continue to support XP after all, and have even come out with a Service Pack 3, which makes the operating system run much faster.
