Why in address space's private regions so many zero bytes?

I'm examining process's address space under windows. When i see content of private regions, i wonder, because there are so many zero bytes (in some regions more than 95%). If more of private regions don't used while application is running, why they aren't only reserved or free?

Thanks to all.

Multiprocessing systems tend to initialize memory for security purposes. Usually, this is to zero. AIX at one time liked to initialize memory to 0xDEADBEAF.
