64 bit

I've ran the 32 bit and 64 bit Windows 7 and I have had a lot of problems with the 64 bit not to mention that it's slow. So next month when I buy the Windows 7 OS I am going to put the 32 bit OS because I know that runs better for me. So in a year when the software catches up I would like to which over to the 64 bit and when I do will I need to do a clean install?

HI, Yes you will, 32 goes to 32, 64 goes to 64 only I am afraid.

absolutly 32>64 or 64>32 has to been done clean

golden,

If you want to change from 32 bit to 64 bit you need to do a clean install.
