+**(185) Can I install FairEmail on Windows?**
+
+Yes, you can if you use Windows 11 or later and install the [Windows Subsystem for Android](https://learn.microsoft.com/en-us/windows/android/wsa/).
+You'll need to [download the GitHub version](https://github.com/M66B/FairEmail/releases) of the app and sideload it,
+which means you need to enable developer mode, please [see here](https://learn.microsoft.com/en-us/windows/android/wsa/#test-and-debug) about how to.
+
+You can install the app via the Windows command line like this:
+
+```
+adb connect 127.0.0.1:58526
+adb install /path/to/FairEmail-xxx.apk
+```
+
+The app isn't available in the Amazon store because Amazon rebuilds all Android apps, and unfortunately, the app doesn't work correctly after rebuilding anymore.
+Amazon never responded to an issue reported about this.
