Hi, I saw that this update for Windows 7 and Windows Server 2008, which was never fully documented and was marked as optional, has now been marked as important by Microsoft. I googled around but there is no info whatsoever, other than that is an update to the Windows Update software itself. Many users reported that when they installed this when it was optional, they found to be tied to "upgrade to Windows 10" nagware. Does anybody know more? http://windowanswers.com/windows-10/kb3138612-update-245022.html#commentlist http://windowanswers.com/windows-10/kb3138612-update-245022.... http://lmgtfy.com/?q=windows+update+kb3138612 http://lmgtfy.com/?q=windows+update+kb3138612
