Microsoft puts back SP2 automatic update

The software maker notified customers of the decision via email on Monday, when it had planned to make SP2 available via automatic distribution. Microsoft said many big companies aren't ready to make the move and need more time to put in place tools to block automatic updates to SP2 until they can fully test their internal applications.

SP2 now won't be available on Automatic Update until 25 August at the earliest, according to the email, which was posted to a number of enthusiast Web sites, including one run by Steven Bink, a software developer based in Amsterdam.

Microsoft representatives were not immediately available for comment.

Microsoft released Service Pack 2 to PC manufacturers on 6 August after a number of delays.

Along with various bug fixes, SP2 adds a new "security centre" that is intended to provide a beefed-up firewall as well as easy ways to tell whether a PC is updated and protected against viruses. In addition, SP2 includes a pop-up blocker in the Internet Explorer browser and updated support for Wi-Fi and Bluetooth wireless technologies.

Compatibility with older applications is a major concern for corporate users. Microsoft on Monday published a list of nearly 50 software applications and games that may encounter problems with SP2. A range of applications are listed in the Microsoft report, including several of the software maker's own products, along with antivirus tools, Web server software and a handful of games.

The auto update delay is unlikely to be a problem for customers. Many companies appear to be in no hurry to install the update. IBM told employees last week to hold off installing SP2 until Big Blue can fully test and customise it. The company's technology department said the delay is "due to known application problems and incompatibility with IBM workstation applications."
