Hi can help me, i would like to change from 32 bit to 64. My computer was bought used and had vista 64 and the person that had it used a upgrade software to 32 bit. I have 8 gigs of ram and the 32 bit is only using 3.5 gigs of it. Now why question is can i do a reformat and then install the OS, i do not have the vista disc. also if you could walk me through doing it or post a link to were i can learn how.
Since it is not possible to 'upgrade' from 32 bit to 64 bit, so you would have to wipe and reinstall anyhow... just do a clean install of Windows 7.
