Upgrading your copy of Windows 10 to the latest helps keep your computer secure and up-to-date. This means there are some changes you should be aware of to take full advantage of your upgrade.
The biggest change is the inclusion of Microsoft Edge, their new browser meant to replace Internet Explorer and compete with Google Chrome. ITS doesn't recommend Edge for daily use but there will be times when Windows will automatically use it to display help and information about your Windows computer.
