I was actually wondering the same thing. Windows 8.1 will be getting support for a number of years yet if I am correct so maybe adapting the Integrate7 script for Windows 8.1 would be a possibility? I would like to put in the work to help do this for Windows 8.1 and Windows 10 both but I wouldn't know how to determine which updates to integrate in which order etc. Tried my hand at making my own Windows7 integration script but then when I found Integrate7 I gave up. Probably did quite a bit of it wrong on my end when I tried rolling my own... Also thinking maybe it would be possible to release a "final version" of Integrate7 with all the updates needed for x86/x64 of all languages included (since at some point Microsoft will probably pull the plug on the updates which will then be hard or impossible to gather).
