Microsoft's latest operating system, Windows 7, could be available earlier than expected, with some reports putting its debut as soon as September.
The software giant initially planned to release Windows 7 in 2010, three years after Vista's launch.
However, some users have been resistant to adopting Vista, which may still lead to an earlier Windows 7 launch.
Some execs are now reported to be saying the operating system could be available before Christmas and there are unconfirmed reports that it could be on the shelves even earlier.
An almost-complete release of the product is expected this week.
