As such it supersedes a ton of other older patches and from this point of view is like a Cumulative Update. That patch was fixing slow update for a lot of people. KB 3145739 is superseding KB 3139852 which was made famous by Noel Carboni about a month ago.

Installing both patches together brings wait times (on the systems I've checked, anyway) back to sane levels. Either patch installed by itself leads to hours and hours of waiting for Windows 7 update. KB 3138612 installs a new program to handle Windows Updates KB 3145739 has a new Windows kernel. I know that sounds like combining beer and cement to make a cheesecake, but there you have it. KB 3145739, on the other hand, is this month's "security update for Windows Graphics Component" - otherwise known as MS 16-039, the security patch that (once again) fixes the way Windows handles fonts inside the kernel.
