Do you have the necessary drivers for Windows 7 on your computer? Have you run the Microsoft upgrade advisor to make sure your hardware is compatible? If you have less than 2 GB of RAM, you'll need to increase it for decent performance because Windows 7 takes at least double the RAM required for XP.
i have an hp laptop with windows XP. I want to install Windows 7. I have downloaded a licensed product but I am not sure which application to click on since there are many in the list.
