At the end of the day, the Google Chrome Installer is still very, very pointless - the only functionality of the so-called installer is to open the download link for Chrome on your default browser. Still, Google has never cared much for the Microsoft/Store in the past, and the company’s newest app for Microsoft’s app store simply reiterates that.
To be fair, Microsoft does not allow web browsing apps on its store unless they are using the EdgeHTML and JS engines provided by UWP, which is potentially the reason behind Google not bringing the actual Chrome browser to the Microsoft Store as it uses Chromium. From there, users follow the usual download link to download and install the browser using the default browser on their operating system. The company today released the Google Chrome Installer on the Microsoft Store, which is a modern Windows 10 web wrapper app that loads the Google Chrome download page. Google is bringing its Chrome browser to the Microsoft Store in Windows 10.
