Windows 8.1 Update 3 Start Menu for non-arm devices?

[yoltboy01]

Sup guys,

does anyone know, if it possible to somehow activate the Windows 8.1 Update 3 Start Menu (Mix of 7 and 8, released for Surface RT/2) on non-arm devices, like my Laptop? 

I like that one and I also know that MS added the exact same Start Menu in Windows 10's early TH1 beta builds, but they replaced it with the RTM one.

Unfortunately there is no way AFAIK. I already looked deep in to this issue, but it seems that microsoft blocked every possible way to backport it. Windows 10 beta builds have some sort of certificate issues and the start menu is buggy as hell. And I don't think you can do anything with arm compiled explorer.exe and twinui.dll
