Windows 10 is a very good OS from Microsoft.I had installed it on my all in one and I am suppressed that it is more faster than my old OS that is windows 7.
One more good feature of it is that they are giving it out free for one year and due to this everyone can ones try the window.But it lakh the program support.
There are very few programs that were specially made for windows 10.But here also Microsoft have done a good job of optimizing it.They have optimized it like that so it could run window 7 and 8 programs and games.So it is not bad to test this window by yourself!
