Android 8.0 Oreo is currently the latest version of Android, and people are waiting for updates on their device. Google Pixel and Nexus Devices receive updates first, but there is no guarantee that your device will receive the latest Android update in the future. Right now if you want to experience how Android Oreo works, you can run it on your Windows, Mac or Linux computer using Android Studio.

Android Studio is the official IDE software by Google, which is used to create native Android applications. It comes with the AVD feature: App developers run their apps on virtual devices instead of using any real physical device. With the latest versions, you can choose to run the Android version in the virtual device.

To run Android 8.0 Oreo on your Windows computer using Android Studio, follow the steps below:

Download and install Android Studio on your computer.
Launch it and wait for the welcome screen.
Create a new project or import a sample project on Android Studio.
On the edit screen, go to Tools> Android> AVD Manager.
Click ‘Create virtual device’ and select a pre-configured Android device from the list.
Under the recommended tab, select the Android ‘O’ 8.0 system image. (click on the download link if it is not available)
Confirm the configuration and finish.
Click on the play / launch icon and launch your virtual device.

You will now see that a virtual device emulator window has been opened, in which Android 8.0 will be run. You can control the touchscreen with your mouse, while additional device control buttons appear next to the emulator. Google apps and services are installed in the virtual devices except the Play Store, so if you want to install a new app on the device, you have to use APK method. You can also create custom virtual devices with your own hardware profile, such as custom screen size and RAM.

AVD is a way to install and run Android OS on a computer, but I believe Android emulators work faster than AVD.
