prateek55, Thank you for using the Dell Community Forum. If Win7 home 64 bit came installed on your computer you will need to purchase win 7 pro from Dell. You will then need to format and reinstall win7 pro.
hi all, please let me know what all options are available in india to upgrade win 7 home basic 64 bit to win 7 pro or ultimate. i need to run programs in xp mode.  the current os came pre-installed with my dell inspiron 15R.  Also, win XP pro is no longer available for sale - original os. so i can't install that on my machine.  let me know options available to run programs in xp mode. Thanks Prateek
