My friend has recently brought a Dell Vostro laptop. The vendor has installed Win7 Ultimate, 32 bit and told us that the OS is a genuine one. But regarding the price (Rs. 36000/-) of the Laptop (Core2duo 2.53ghz processor with 512MB graphich card, 2 GB RAM & 2MP webcam) with Win 7 installed we have doubt about OS genuineness. Is there any way to find out if the OS is genuine or pirated without connecting to Internet?
