Bluestacks: Where are my apps?
You need a custom launcher to see all of your apps. A launcher is what displays your home screen and everything on it.

Method 1 (recommended):


Go to the Play Store, and search "launcher"
Pick one you like, and download it (I recommend Nova)
When you press home, it will ask you to select an app. Choose Nova Launcher, then click always.
To see all of the apps, click the icon that looks something like this:




Method 2:


Search Google, "android launcher apk"
Choose from any of them, and open the link.
Click download. Be careful, sometimes there are advertisements that look like a download button
It will start downloading. To see the progress, open the notifications
When it is done, click on the notification
A screen comes up that tells you the details of the app and it's permissions. Click install
When it is done, press the home button
It will ask you to select an app. Choose Nova Launcher, then click always.
To see all of the apps, click the icon that looks something like the icon above
