can 32 bit programs utilize more memory while running in 64 bit environment??

Hi..s,

I am not a professional coder and i do not have in-depth knowledge about memory addressing. Recently i have decided to upgrade my Window 7 to 64bit. Now i have a doubt that whether a 32 bit program can utilize more ram memory (i.e. >4GB) while running in 64 bit environment? If so, any performance improvement will be notified in real time usage.?!?.

No not at all. Performance will be more or less same if other Hardware are identical.
