I have installed windows 8 with the activation key in my Dell laptop as it was there pre-installed in my pc. I have started to go through the basic functionality and found it little bit unfamiliar as because the start-up was too slow and also the start up was clumsy.
There was also turbulence to go through the dual boot and about the web access. But the worst thing was despite of being so feature enriched os it is still getting hanged very early and not being supportive for the users if hardware configuration is considered.
