I doubt there are any free upgrades to Win 7 nor do I think you will find any for 250.00 INR = 5.29605 USD. The leaset expensive way would probably be through a school if you are a student or work for the school.

Hi, Do you mean it's a Dell computer. If so, you can contact Dell to check the Windows Vista to Windows 7 upgrade method.Vivian Xing - MSFT
