If you already have a copy of classic Minecraft (purchased before October 19th, 2018 ), you can download the Bedrock Edition (formerly known as the "Windows 10" edition) of Minecraft for free. If you own a copy of Minecraft on Mac, you can download the Bedrock Edition of Minecraft for free on a PC. Go to https://account.mojang.com/login in your browser. Enter your Minecraft email address and password, then click Log in. This will log you into the Mojang account that you used to buy Minecraft. Make sure that you're using the account with which you bought your initial version of Minecraft. This heading should be near the middle of the page. You'll find this button to the right of the "Minecraft for Windows 10" heading. You should be redirected to the Microsoft Store. It's to the right of the Minecraft logo. You may first be prompted to log into your Microsoft account. If so, enter your email address and password before continuing. Once Minecraft's Bedrock Edition finishes downloading, you should be able to find it in the Start menu.
