It was ultimately succeeded by Windows Vista in 2006 after several delays in its development, although many users opted to stay with Windows XP due to Vista's higher system requirements and initial instability. It is the first consumer version based on the Windows NT codebase, succeeding both the NT-based Windows 2000 Professional and the 9x-based Windows Me. It was released to manufacturing on 24 August 2001 and later made generally available on 25 October 2001. Microsoft also said today that it is resuming automatic distribution of Windows Vista SP1, which it suspended last week at the same time it put the brakes on XP SP3.Windows XP, codenamed Whistler, is an operating system developed by Microsoft.

So far, company representatives, including XP SP3 release manager Chris Keroack, have said only that it would happen sometime in "early summer." Other sources, however, have pegged June 10 as the probable delivery date via automatic download. Microsoft will eventually push XP SP3 to users who have set Windows Update to automatically download and install important updates, but it has not nailed down a date for doing so. The company has also added filters to Windows Update so that machines running RMS will not be offered Windows XP SP3, the spokeswoman said. Meanwhile, a company spokeswoman said in an e-mail that Microsoft would make the fix generally available "over the next month."

The company also posted a 316MB stand-alone installer on its download site and recommended it to users updating multiple machines.
