Though it does not make any practical sense to run Android OS on your Windows, here are a couple of ways to do it.

1. BlueStacks
The application will not run the full Android OS on your system, but it can be used to run Android apps on your computer or laptop. It also allows you to download apps from Play Store. BlueStacks is the most widely used and reliable method to run Android apps on your device.

2. Official Android Emulator<
The Emulator is part of Android SDK. It is used to run Android Operating system on your PC. It is used by the Android developers to test their apps. But the emulator is little slow and cannot be used for day to day operations.
Download Android SDK, open SDK manager program and select tools. Follow instructions to create Android Virtual Device.

3. Android-x86
This is a community project aimed at porting Android to x-86. Right now it is supported only on a few specific devices. Please note that this is an experimental project. It may not be stable on your device.
