    I am still on DOS!!! Will it upgrade to Windows 7? I have never really liked Windows products, but think it is time for me to upgrade. I have a lot of information on my computer and need to transfer it. Any suggestions?

    I am done….they fouled up with Vista – companies roll back from Vista back to XP – and Microsoft comes up with Windows 7 and you can’t even upgrade from WinXP? Brilliant….

    The only thing you can do is either clean install Win 7 or upgrade from XP to Vista and then from Vista to “7″.
