Microsoft Corp. accidentally added the final 64-bit version of Windows Vista Service Pack 1 (SP1) to Windows Update yesterday, even though it’s repeatedly said that most users won’t be offered the upgrade for weeks. Some users of the 64-bit edition of Vista were able to download and install SP1 yesterday. By Friday, Microsoft had pulled the service pack from Windows Update (WU), according to reports posted to a support newsgroup.
A major update to Microsoft’s Windows Vista operating system could leave computers vulnerable to hackers and malware as the service pack prevents several widely used antivirus programs from operating, the company said. The list of security products that Windows Vista Service Pack 1 blocks includes Zone Alarm Security Suite 7.1, Trend Micro Internet Security 2008, and BitDefender 10. It also blocks the 2008 version of the Jiangmin antivirus product.
Microsoft has stopped automatically distributing a prerequisite piece of software for Vista Service Pack 1, following customer complaints that it had caused system problems. Servicing stack update KB937287, released last week, contained updates to Windows Vista installation software, and was billed as being “necessary to successfully install and to remove Windows Vista SP1 (Service Pack 1) on all versions of Windows Vista.”
