Can a Windows Vista Home Premium 32bit system be converted to a 64bit system? (Without reinstalling the system? or in any other way?)
 
When I installed a new system disk on this computer an additional disk came with it that read 64bit. Can I use this disk to do a clean install?
I don't have the disk in front of me at the moment.
