I was thinking to get the Windows 7 32 bit upgrade package, as I am currently using the Windows Vista 64 bit. I also know that when I get the upgrade package it just install over Vista, but once I have install the Windows 7, if I want to format my PC (Personal Computer) some time down the line, will I be able to use the upgraded disc of windows 7 to format or re-install? Does it will work only with the windows vista as the OS at the point of formatting? Please help me and suggest some idea or suggestion what to do. Thank you.
