Microsoft has pulled a Windows 7 security update released as part of this month's Patch Tuesday after discovering it caused some machines to become unbootable.
Update 2823324, which was included in the MS13-036 bulletin, fixed a "moderate-level vulnerability" that requires an attacker to have physical computer access to be able to exploit a targeted computer, Dustin Childs, a group manager in the Microsoft Trustworthy Computing group, wrote in a blog post published Thursday evening. The company has now pulled it from the bulletin and is advising at least some Windows users who have installed it to uninstall the update following the guidance here. MS130-26 was one of nine bulletins released on Monday to fix 13 separate vulnerabilities.
"We’ve determined that the update, when paired with certain third-party software, can cause system errors," Childs wrote. "As a precaution, we stopped pushing 2823324 as an update when we began investigating the error reports, and have since removed it from the download center."
