Microsoft's policy of not allowing any third-party browsers in the Microsoft Store to use their own rendering engine, and instead forcing them to use the rendering engine included with Microsoft Edge, has prevented popular browsers like Chrome and Firefox from showing up on the app store in Windows 10.
While Google has generally shown no interest in bringing most of its app library to the Microsoft Store, it has decided to make a bit of effort when it comes to what is arguably the company's most popular application on Windows: the Chrome browser. Microsoft's restrictions still bar the company from releasing the browser in its entirety on the Store and, so, as part of a rather amusing workaround, Google this week published the 'Google Chrome Installer' on the Microsoft Store.
The app is unfortunately only a web wrapper, whose sole purpose is to allow you to access the download page for Chrome, which then forwards you to your default browser to complete the download for the actual .exe installer for Chrome.
As far as apps go, this one is quite the inane addition to the Store and the fact that you're re-directed to your default browser anyways (if you have a new machine that doesn't have Chrome, that's most likely Edge) makes the whole process all the more pointless.
Published earlier this week, the app has a single, 1-star review complaining about the lack of functionality, as the user is no doubt confused by what they assumed was their favorite browser not working as such.
If your disdain for Edge is such that you'd can't even bring yourself to use Microsoft's browser for the minute it would take to download Chrome, you can download the Chrome Installer from the Microsoft Store here.
