A non-patch security update for Windows 7 and Windows Server 2008 R2 was causing systems to reboot. It's been a rough few months for Microsoft's update quality control.



From ZDNet:

Microsoft has withdrawn an update released this past Tuesday due to user reports of system reboots after installation.

The update released as described in Microsoft Security Advisory 2949927 added SHA-2 hash algorithm signing and verification for Windows 7 and Windows Server 2008 R2. It was one of three proactive security feature updates released on Tuesday in addition to the eight patches of Windows and Office.
