What's the difference between upgrading Windows 10 using Windows Update or ISO file

On November 12th, Microsoft finally began rolling out its first major update for Windows 10 (build 10586). On the same day, the New Xbox One Experience (build 10586) was made available to everyone too, and now we’re just waiting for Windows 10 Mobile, which should be arriving pretty soon. The Windows 10 November update, or version 1511, brings a lot of changes, improvements, and features that according to the software giant make the operating system mature enough to be recommended as a daily driver for organizations. Among the many changes, which you can learn more in our previous article, Microsoft is including performance improvements to help users perform tasks faster than in Windows 7. Cortana brings handwriting recognition and “missed call notifications” features, Microsoft Edge includes changes that make daily browsing more stable and secure, there are new and updated apps, a bunch of new features on the Settings app, and a lot more. For those users who have been using Windows 10 since launch, this is an update they want to install. Microsoft is currently pushing the November update through Windows Update, but it seems that not everyone is getting the update just yet, and of course, there could be a few reasons for this to happen.
