Wine running on my ASUS ZenPad 8
Wine is a program ("compatibility layer") that can run Windows programs under Linux and MacOS and is widely used from all sorts of purposes ranging from running Microsoft Office to even games. Wine has become very popular and useful tool for non-Windows users worldwide, and with the release of Wine 3.0, it's finally making its move to Android. You can access and download all the builds here. It currently supports x86 and ARM architectures.
While it's working, it's still very much a work-in-progress. Don't expect running your favourite games and apps just yet, although you're welcome to try.
