There are claims that Microsoft could release the first Service Pack (SP1) for its newly released Windows 7 operating system fairly soon, possibly in the final quarter of this year itself.

This time, a Malaysian site, TechARP.com, which has incidentally been spot on in forecasting the Service Pack schedules for Windows XP and Windows Vista in the past, has speculated that the SP1 for Windows 7 would land as early as in the final quarter of 2010.

"The earliest Microsoft can realistically release Service Pack 1 for Windows 7 is in the last quarter of 2010", the website noted.

Initially, Microsoft was to follow a 22-month development span for the Windows 7 SP1, but later on it has reportedly abandoned its plans to address unidentified number of "serious" issues with the operating system.

This schedule would go well in line with its previous timetable for SP1 for XP and Vista. The SP1 for Windows XP was released around 10 months after the launch of the operating system, while the Vista SP1 was landed just around a year after the operating system was launched in January 2007.
