Microsoft has released the first preview version of its Android apps support in Windows 11. I’ve installed the preview version on two systems — a gaming rig with a Core i9 11900K and Microsoft’s Surface Pro X — to get a feel for exactly how well Android apps run on Windows 11. The experience of installing apps is very simple.
