An unofficial Windows XP Service Pack has been made available on the Internet to create havoc to anyone that installs it.
Here is one quote from Microsoft:
"Anyone who installs this thinking they are getting SP3 (even as a preview) is being grossly mislead and is posing a significant potentially non-recoverable risk to their PC and data," wrote Mike Brannigan, an enterprise strategy and senior consultant at Microsoft.
So if you come across a link with a that asks you download the software then please don't and try to avoid it.
Microsoft has said that its priority is Windows Vista, the next major release of its operating system.
While the company does have plans to release XP SP3, it has not provided details on what the service pack will contain. Microsoft has issued a statement saying that the "content on the unofficial website(s) does not represent Microsoft's plans for Windows XP SP3."
