Microsoft Holds Off Installing Update

April 23rd, 2013

Microsoft is urging users to who haven’t installed it yet to hold off on MS13-036, a security update that the company released earlier this week to fix a dangerous security bug in its Windows operating system. The advice comes in response to a spike in complaints from Windows users who found their machines unbootable after applying the update.

The MS13-036 update, first released on Tuesday, fixes four vulnerabilities in the Windows kernel-mode driver. In an advisory released April 9, the company said it had removed the download links to the patch while it investigates the source of the problem:

“Microsoft is investigating behavior wherein systems may fail to recover from a reboot or applications fail to load after security update 2823324 is applied. Microsoft recommends that customers uninstall this update. As an added precaution, Microsoft has removed the download links to the 2823324 update while we investigate.”

The problems with the patch appear to be centered around Windows 7 and certain applications on Windows 7, such as Kaspersky Anti-Virus. Microsoft has issued instructions on how to uninstall this update in the “resolution” section of this advisory.

Update, Apr. 23: Microsoft has re-released the problematic security update to address the problems that some Windows users were experiencing with the MS13-036 patch. The new update, KB62840149, replaces the faulty one, which was KB2823324.
