Microsoft may have little choice but to support XP for an extended period since most of its business customers have not upgraded to Windows Vista.
"In an unprecedented move, Microsoft (NSDQ: MSFT) has committed to providing support services for its soon to be retired Windows XP through 2014 -- a full 13 years after the operating system was originally released.
In a letter sent to customers this week, Microsoft senior VP Bill Veghte said the software maker will provide security patches "and other critical updates" for Windows XP until April, 2014.
"Our ongoing support for Windows XP is the result of our recognition that people keep their Windows-based PCs for many years," Veghte wrote."
In addition to supporting XP through 2014, Microsoft is now actively promoting a program that allows customers to downgrade Vista systems to XP through a loophole in the company's licensing terms. Microsoft's software license allows customers who purchase a copy of Windows to install and run a previous version of the OS at no additional cost."
