A direct upgrade is not possible. However, you are eligible to purchase an upgrade edition of Windows 7 at the reduced cost. You can then use Windows Easy Transfer to backup all of your files and settings, perform a clean installation of Windows 7, restore your files/settings, and reinstall all of your programs. Unfortunately, that's the only way as Microsoft chose not to support upgrading from Windows XP to Windows 7, only Windows Vista to Windows 7.
I am planning to upgrade my laptop from Windows XP home (32 bit) to windows 7 professional (64 bit). please let me know whether it possible or not. If it is what are the means and methods to achieve (I mean what to buy and how much it costs).
Thanks all.. happy thanksgiving..
