Windows 10 is here to stay, and Microsoft is make a really concerted effort to get their new operating system into as many homes and offices as they can, as quickly as they can. The latest version of Microsoft Windows is an improvement over Windows 8, in my opinion; more user-friendly in most areas.
That said, new users will still have questions on upgrading and using this new version, and to that end I offer you some helpful links:
Microsoft themselves - straight from the horse
Windows Central - a long established site
Windows 10 Forums - users helping users
