Microsoft’s KB3126446 update for Windows 7 /8.1 makes PCs and Laptops go in a reboot loop.
Botching up updates has become a habit for Microsoft and its engineers. The new update, KB3126446 released yesterday as part of February 2016 Patch Tuesday seems to be pushing Windows 7 computers into a longer reboot loop.
KB3126446 update was issued by Microsoft to fix security vulnerabilities in Microsoft Windows, as part of bulletin MS16-017 and is available for Windows 7/8.1 and Windows Server 2012 R2. However, when users of Windows 7 Service Pack 1 apply the patch, their PC/laptop goes on a reboot loop.
“This security update resolves a vulnerability in Microsoft Windows. The vulnerability could allow elevation of privilege if an authenticated attacker uses Remote Desktop Protocol (RDP) to log on to the target system and sends specially crafted data over the connection. By default, RDP is not enabled on any Windows operating system. Systems that do not have RDP enabled are not at risk,” Microsoft says.
Basically, what it could happen after installing the update is for your PC to reboot several times, but the number of restarts is not yet specified. But once this reboot loop comes to an end, you should be able to start re-using the computer normally, with no other issues likely to be caused by this update.
Microsoft has acknowledged the problem and explained that “you may have to restart the computer multiple times after you install this security update on a Windows 7-based computer that is running RDP 8.0.”
