While Microsoft learned to report all 4GB RAM the 32 BIT versions will use most of this ram but not every byte. Frankly this is no great loss. Take the free upgrade.
Sorry, forgive me as I stop here and not duplicate the old 4GB 32-bit Windows discussions.

so i recently got a new laptop, and it comes with a free win 7 upgrade. currently i am running vista home premium 32 bit and got it with 4 gigs of ram. i am a light gamer. the upgrade will give me win 7 home premium 32. i am planning to get the upgrade and want to know if it is possible to get the upgrade to 64 bit for less money? also is it worth it on my system? because i dont know if 32 bit will recognize all my ram.
