OK...when is it going to be released in July?
And what is the bit thing 32 and 64?
(1) Dunno. The great Lords of Microsoft will no doubt get some aging bunch of has-been pop stars to sing about it when the time arrives.
(2) Basically, most people use the 32 bit version of XP and Vista.
The 64 bit version in theory allows you to have vast amounts of memory.
In practice, few programs support it, and it crashes a lot.
