Ok guys, thanks for the help. I successfully installed Windows 8 on my Desktop PC and my brothers laptop. It is working perfectly fine and i am very happy with it's performance and appearance despite some minor qualms(Why Microsoft Account everywhere :fp2
. I got the hybrid graphics issue solved by downloading the latest drivers from the vendor. Almsot all drivers were installed autmatically and some of them got installed through windows update.
I have also managed to easily activate it using KMS activator on both systems and it is working fine since i can use Store + Updates and i don't see any sort of watermark. I can also customize the appearance and stuff. I don't understand why you guys had trouble with activation. It is a simple click process and even if requires internet access, i don't see any harm in it.
Overall, this is really a nice windows. The improvements are neat. Now i will IA install in my own laptop as well.
