Vista Tablet -> 64-bit professional

Hi all,
I just burned my 64-bit professional ISO file onto a bootable DVD and am about to install it onto my current 32-bit vista... Before I proceed, I want to make sure that when I do a clean install and erase everything on my laptop, nothing will happen to my tablet right? As in, after I performed the clean install, my tablet will retain its files necessary for the tablet/touchscreen functions to run properly right? Thanks... just want to double-check before I go ahead and delete everything!
