I have 6 installs, all upgraded/updated/whatever to the 17031 build. 1 of them I had to do one of the files twice, all else went fine. I use this order, rebooting after each file. 1 KB2919442 Preparation Update 2 KB2939087 Preparation Update 3 KB2919355 Update 1 4 KB2932046 Supplement File 5 KB2938439 6 KB2937592 Yeah OLD guys!
I have followed the order and restarted at every steps but of course maybe my case only the PC eventually stop working and sometimes need to restore from a backup of recovered state. I am just provide information of my current situation but before update my PC is working fine.
