I've read this question, and of course, there, the answer was "you can't, because the architecture is different."
But that's not necessarily the case anymore. Many Android devices, like mine, now have x86 processors and also the specs to run Windows. Thanks to Remix OS and Android x86, many x86 desktop computers (and tablets, etc.) now run Android.
So, is there any way to virtualize Windows on Android if you have an x86 device?
