It’s been a while since Microsoft has officially launched the Chromium-based Microsoft Edge browser. However, a lot of people are just beginning to notice this feature-packed browser. Edge introduced revolutionary browser functionalities that provide a better browsing experience.

Some of these features include support for Progressive Web Apps (PWAs), Immersive Reader, Read Aloud, nitty-gritty options like quiet notification requests, and a host of important features that address privacy and security concerns from users.

If you have not tried Microsoft Edge yet, now is the best time to do so. You can easily download and install this browser for your Windows 10 or macOS computer. Most likely, the installation will go along without any problem, but for some users, the following error appears when installing Microsoft Edge on Windows 10:

“There was a problem installing Microsoft Edge, Error Code: 0xa0430721”
