Windows 10 , we can say that till now one of the most powerful and user friendly operating system as of now. The biggest advantage of this OS is that it's really easy to use and simple to learn and very flexible to install our required software to perform our daily basis task.
Now also as per security concerns windows 10 did very good job because now they are providing free Windows defender antivirus which work very good on moderate level.
The best and most favorite thing is that it's usage means it's really simple to use and attractive user interface. Initially when windows OS got released like Windows 95, Windows 2000, Windows XP all have the same concern that were the booting or processing speed.
Where Microsoft always lagging but from the Windows 7, Window 8 and now in Windows 10 there is lot difference we are now able to see specially in term of processing speed.
Specially in in windows 10, the booting process is much faster that any other OS as of now.
The other most important factor performance of operating system means now if you want to perform the multitasking work that is also possible to perform very efficient way.
Inbuild Antivirus: Now a days Microsoft offering in build windows defender antivirus which performance also quite impressive because I must say I am also using Windows 10 and due to this antivirus I am not getting any virus issues on medium level.
So overall my personal recommendation is Windows 10 OS and once in life please try it. Review collected by and hosted on G2.com.
