Microsoft is rolling out its new Windows 10 Operating System (OS) and unlike the release of Windows 95, nobody is expected to line up to purchase the product. However, it seems like the aim is to make it easier for the users to upgrade to the latest OS.
It is not necessary that the user be registered for the Windows 10 update since it is automated for Windows 7 and Windows 8.1. The auto-download will be run for those who have enabled the automatic Windows updates.
Users with storage less than 3GB storage, and that combined with the amount of internet data the upgrade takes up might cause difficulties to some users.
The up side is that the download and upgrade can be avoided by simply disabling the automatic updates. The files which have already been downloaded can be deleted by using the Microsoft Disc Clean Up Utility.
