Last year Microsoft launched a preview of its Android subsystem for Windows 11 enabling you to run Android apps on Windows 11. Initially it was only available in the US but now Microsoft has expanded the preview to the UK.
With the preview Android app as available for Windows 11 via the Amazon Appstore which you can get from the Microsoft Store. You will need an Amazon account to get the apps but there are ways of sideloading apps via this guide.
To get started install the Amazon Appstore from the Microsoft Store and open the Amazon app store app.
After you open the store, you can sign in with your Amazon account
Unfortunately there is an extremely limited set of apps in the store so for now you can only do limited testing (unless you sideload Android apps on Windows 11)
