Sideloading on desktop and tablet
This should not be necessary in most cases, as Windows 10 has sideloading enabled by default
- Go to Settings > Update & Security > For Developers
- Select "Sideload apps"
App packages can be installed simply by double clicking the app package file, just like you would with a traditional program's installer file. To use this, simply navigate to your app package (.appx) or app bundle (.appxbundle) file, and double click it.
The App Installer launches and provides the basic app information as well as an install button, installation progress bar, and any relevant error messages.
Click install and let it run.
