Microsoft used this month’s Patch Tuesday cycle to release a new cumulative update for Windows 10, this time aimed at both pre- and post-November Update versions.

Since this was released on Patch Tuesday, the monthly cycle that brings us security fixes, the cumulative update is mostly supposed to fix security bugs and improve performance of the operating system.

It’s worth noting that the patch is numbered differently for Windows 10 build 10240 and Windows 10 build 1511, namely KB3124263 and KB3124266, respectively, but the included fixes are exactly the same.

Here’s what the patch brings on Windows 10 in terms of security fixes:  

3124605 MS16-008: Security Update for Windows kernel to address elevation of privilege: January 12, 2016
3124901 MS16-007: Security Update for Windows to address remote code execution: January 12, 2016
3124584 MS16-005: Security Update for Windows kernel-mode drivers to address remote code execution: January 12, 2016
3124904 MS16-002: Cumulative security update for Microsoft Edge: January 12, 2016
3124275 MS16-001: Security update for Internet Explorer: January 12, 2016
3118753 Microsoft security advisory: Updates for ActiveX kill bits: January 12, 2016
It’s also important to know that the patch has a known issue that prevents it from being offered on a number of Windows 10 computers. Microsoft says that PCs running Citrix XenDesktop won’t get the patch because of a compatibility issue.

“Because of a Citrix issue with the XenDesktop software, users who install the update will be prevented from logging on. To stay protected, Microsoft recommends uninstalling the incompatible software and installing this update. Customers should contact Citrix for more information and help with this XenDesktop software issue,” the company explains.

As usual, the cumulative update is shipped via Windows Update and requires a reboot, so make sure you save your work before anything else. Creating a restore point could also be a good idea given the fact that so many cumulative updates fail to install lately.
