The development studio CodeWeavers is currently working on an emulator which would allow users to run Windows 10 apps on Android tablets. Soon, they'll be releasing its technical preview for the free-software, which will bring several Windows apps to certain tablets with x86-architecture.
As a result, several third-party games and apps from Windows OS can be enjoyed without the need to juggle with several devices. Codeweavers has already released the CrossOver emulator which runs Microsoft Windows apps on Apple´s Mac OS X.
However, it's worth noting that the emulator designed by CodeWeaver will not work with many existing Android tablets. The minimum requirement for running the software is X86 architecture or an Intel Atom chip paired with at least 2GB of RAM. The need is of Intel, but most Android tablets available in the market today are equipped with ARM's competing processors. Only devices like Nokia N1, Asus ZenFone 2, Lenovo Yoga 2, and Dell Venue 10 700 series run on Intel's architecture.
The software will execute Classic Windows apps only. As most Android tablets don't meet the hardware requirements, it will interesting to see how several Windows app will function on Android-based devices. The apps will get emulated on Android, and thus their performance is not likely to be as solid as on Windows.
Few days back, Google was also rumored to release apps for Windows 10. As of now, there is no confirmation on the rumor, but if apps would move on to different ecosystems, users will certainly get a better user-experience.
