Microsoft releases new updates on every Tuesday.
This Feb 9th, 2016 we hadsimilar updates, which included KB3126446.
Luckily, this update is meant for users with Remote Desktop Protocol (RDP) enabled.
As part of thesecurity bulletin MS16-017, this update (KB3126446) fixes a security problem in Microsoft Windows.
This will cause elevation of privileges, like running applications or programs with Administrator privileges.
So its like an error-gate being closed, but a new problem crops up due to this fix.
The number of restarts can vary from system to system.
The reboot is common for all updates.
But going into a loop, is not seen these days.
The KB3126446 update mainly affects the Enterprise and Ultimate editions of Windows 7.
But if you are running RDP 8.0, then all supported editions of Windows 7 are affected.
The size of the update is around 1.5 MB.
What is Remote Desktop Protocol (RDP)?
This is generally used for troubleshooting purposes.
But generally, you give access to your PC using RDP to people you trust.
Some of them can be hackers.
The only thing that will prevent this problem, is not to load the update KB3126446.
But if you have updates automatically installed on, then it will install, without your intervention.
The only remedy in that situation is to uninstall it again.
But this will pose a security threat if somebody accesses your system using the RDP.
Also this particular problem, arises if RDP 8.0 is installed on your system.
By default, this is not enabled on your system.
This is the only solution in the current scenario.
