Hi I've just tried the latest Wintoolkit build 1.4.43.1 and two updates don't integrate properly: KB2962409 and KB2955164. They show up in Windows Update. What is curious is although the *.MSU's are 49.6 MB and respectively 97.4 MB, after running Windows Update they show up as being only couple of Kbytes large (~200 KB). Thanks kukubau
