Hi. I was making preparations to change from Win7 to Win10 when I remembered that a couple of portable programs I use won't work with certain Windows Updates. Trying to open those programs after a rogue Update results in a message saying “The application was unable to load a required virtual machine component. Please contact the publisher of this application for more information.” The only way to cure this (apparently) is to uninstall the rogue Updates. (If you're interested, they are: KB3045999, KB3022345, KB3071756 and KB3060716. The last two came just a couple of weeks ago.) Having read that Win10 Updates are mandatory, I installed Win10 in a virtual machine and tried my portable program on it. As I feared, it gave the aforementioned error message. Looks like I'm sticking with Win7 then. But surely lots of folk use portable programs and many of these will no doubt be failing with Win10. Does anyone have any experience of this or perhaps know of a cure/workaround?
