32 or 64bit OS?

[sak777]

I never wondered before now and so didn't know, but how do you check what type you have? Also, does this mean that no new releases of dolphin will be let out for a 32bit OS?

There will be a new X86/32Bit and there will be a 64bit version in the future.
But the 64bit version will be faster I think.
And what do you want to check? You OS version?
Just check your system properties and there will be the version of your OS e.g. Windows XP Professional, Windows Vista Home Basic or Windows XP X64 Professional and Windows Vista 64 Ultimate.
