I am using Windows 10 more than 1 year its really great Operating System for hard work. Its officially released in 29 July 2015 but when they first time release they have some problem but day after day Microsoft Windows 10 improve a lot.
Installation process is same as older Windows 7, 8 or 8.1 when installation complete system is reboot and after that new features you can see. Like voice reorganization system that is Cortana, Skydive(One Drive), Mail Account etc if you set up with continue installation process then you can get some different option but for this installation process required internet connection.
If we talk about user interface its really great just like we are using a tablet not an windows. Improved Start bar that we can use full screen start bar as well as normal size convertible start bar. In the new built version of this windows included Microsoft Office so you never need to again install any other office suit. One Drive also gives us one great feature that is if you tab keyboard key print-screen then this take automatically screen shoot in one drive picture folder. A lot of shortcut key they added so you need to understand that key then you can easily open any application using keyboard without search application.
Features of this operating system till date updates is we can scheduled windows update because when they first lunch windows 10 we cant stop automatically windows update but now we can stop as well as we can scheduled updating system Not only this one great feature they included in this system that is Power Shell here you can access Linux Terminal so here work all shell command so you never need to install Linux operating system separately. System Software updates and driver update also updated automatically in the windows update.
Service and support is really fast of the Microsoft they gives up really fast feed back as well as they can chat with client and I like that live chat support system of the Microsoft.
