About 50,000 pirated DVDs of Microsoft Windows 7 are estimated to have been sold here since the official launch on October 22, generating unaccounted business of around Rs 50 lakh (nearly $100,000).

The reason for the allure of the pirated versions: These cost Rs 40-Rs 250 in Naza Market in Hazratganj here, drawing buyers from not only the rest of Uttar Pradesh and neighbouring states like Madhya Pradesh, Bihar and Uttarakhand but also Nepal and Bangladesh.
