It was the best laptop.I have bought this laptop for 45, 000 rupees.It came with windows 10.It installed its own software and the antivirus detecting software for free.It contains the lenovo store in which we can dowload all types of applications as like in the mobile.And it contains the best browser for fast downloading of files.It provides the services whenever laptop is effected by the any virus.When virus is detected, lenovo laptop itselfs optimises the virus and protects the laptop.And it has the dolby sound system with hd videos.We can able to upgrade our windows whenever needed. "THANK UUU"
