How to use Google Play on PC
The fastest way to access the store from Windows is by using an emulator of the likes of BlueStacks. It's one of the most stable and user-friendly options. Once it's ready, you'll be on the main screen of the emulator, very similar to the home screen of any phone or tablet.
If you take a look at the upper part of the interface, you'll see several sections. You should be interested in visiting My Applications, the option on the utmost left side of the upper menu. Once you access this option, you'll see several icons, some of which correspond to apps installed by default and one in particular called System applications that includes different basic tools.
Once there, you'll see several apps, including Google Play: the emulator includes a shortcut to the Android app store so that you only have to click on it to start downloading apps. The truth is that the search engine available from upper right-hand side of the interface is the actual Play Store search tool. Therefore, if you want to download a specific app, just search for it. There's no need to go to Google Play each time you want to download a new app.
