Well, even though i am hearing too much appreciation of win 10, I have also come about various reviews about win 10 from win7 users.

Though it might have good interface and features, but also does it severely lack proper driver support in most of the laptop pc .
Not even old models like my Sony Vaio vpccb15fg(2011 launch) but also newer models like my friend's HP 15ac179tx(2016 launch), both having qualified the windows 10 compatibility test in Windows upgrade advisor, could not successfully...

It's a Genuine product ... Update all feature after installation. I recommend it to buy this product from this seller.
Thanks to Flipkart & also the seller to send it near my door step at right time.

Packing was superb as well as the delivery was also before time!! Regarding the product genuine windows 10 pro and works absolutely fine without any problems!!

This product is really all times great. Thanks to Microsoft for building up such a nice product. Windows 10 64 bit is really very helpful for graphic work and it is fast interface of this OS is also very simple. More over thanks to Flipcart for prompt delivery and give the original product.

work good, its genuine, but be careful about the editon, its not a market retail key. its Microsoft MAK key what i got. but i has no efficiency issue. its works like the same as retail key. may be in future, i may face any difference in customer care support. till then its excellent.

I got a Blocked key Product Delivered First Time. I am disappointed and inform the matter with Flipkart. I got Awesome Service support from their side. They Replaced it by a Genuine one. Thanks Flipkart for your Support

It is a genuine microsoft windows 10 pro 64 bit. I loved this product easy to install and simpler than previous versions.
Genuine windows are more secure as they get updates regularly from microsoft.
