I do not believe you can use the "upgrade" versions of Windows 7 to go from 32 bit to 64 bit without doing a clean install...so in this sense you need to back-up your files (always do it anyway)...and yes, if you do a clean install you will need to reinstall stuff...

If you go from 32 bit to another 32 bit OS...you will have the option to install right on top of Vista, so you wouldn't have to reinstall anything, but no matter what...backup your computer before you ever make any major changes.



If I die today, I'm happy how my life turned out
