Microsoft Paint is the updated original Paint app for Windows 10 released by Microsoft.
Microsoft has released Paint in the Microsoft Store, but most people see "redeem a code" instead of "Get." We were able to find the download link, and here is the official Paint app from Microsoft. You can try the Author link at the top of this page if you prefer to try and download Paint from the Microsoft Store.
Download and double-click on the Msixbundle file. If you have Paint installed, you will be offered the option to reinstall or launch. If you don't have Paint installed, you will be prompted to install Paint. See our screenshots below.
