I recently built a new computer and put the wrong installation of Windows on (32 bit), meaning I cannot use all of my RAM. I would like to upgrade to the 64 bit version, though I already have downloaded many programs and games which would total to around 30 GB give or take. I don't have the kind of data usage with my ISP to re-download this much data again, until next month (total GB will be higher as time goes on).
I know there is Windows Easy Transfer, but it is not so much my data itself I'm worried about, it is more having to re-download and install a bunch of games and applications. Is it possible to perform an upgrade from 32 bit to 64 bit without this loss?
